# How to get citric acid from lemon (3 reactions)

Lemons are used in cooking and baking but did you know they can also be used to create citric acid?
Citric acid is a natural preservative found in lemons.
It’s often added to food to prevent spoilage.
But did you know that citric acid can also be created using 3 simple chemical reactions?
In this blog post I’m going to explain you how to make citric acid from lemons.

## Citric acid+ sodium hydroxide 🡪 trisodium citrate + water

Citric acid is a natural preservative found in lemons and limes. It is used in many products such as toothpaste, mouthwash, and deodorant. It works by inhibiting the growth of bacteria and fungi. It is also used in making soap. Sodium hydroxide reacts with citric acid to form trisodium citrate. This reaction is reversible, meaning that if we put citric acid into solution containing sodium hydroxide, the citric acid will react back to citric acid.

## Equation 3

$$\ce{2NaOHaq + H3O+aq -> Na2CO3s + 2H2Ol}$$ This equation explains how sodium hydroxide NaOH reacts with citric acid CA. In this case, CA acts as a reducing agent because it is oxidized to carbon dioxide gas CO2, leaving behind two molecules of water H2O.

## Equation 2

$$\ce{CaOH2 + C6H8O7 + 8H2O -> CaC6H4O72 \cdot 4H2O}$$ This equation explains how calcium hydroxide CaOH2 reacts with glucose C6H8O7. Calcium hydroxide is formed from lime calcium oxide CaO reacting with water. Glucose is oxidized to gluconic acid GA.

## Other FAQs about Lemon which you may be interested in.

Lemon juice contains citric acid, which is responsible for sour taste. It is found naturally in lemons. Citric acid is a weak organic acid. Its dissociation constant pKa is 3.1. This means that it is not very acidic but it does react readily with bases. It is used in many industries such as pharmaceutical, cosmetics, food processing, textile industry, paper making, leather tanning, and metal plating.

## Tricalcium dicitrate + sulfuric acid 🡪 citric acid + calcium sulfate

Citric acid is a weak acid. It is a trisodium salt of citric acid. Tricalcium dicitrate is a compound containing three calcium ions and two sodium ions. Calcium ion is a cation positively charged while sodium ion is an anion negatively charged. In chemistry, we call these ions as “cation” and “anion” respectively. Sulfuric acid is a strong acid. It is a dihydrogen monosulfate. Sulfuric acid is also known as H2SO4. It is a white crystalline solid. It is a colorless liquid at room temperature. It is highly corrosive. It reacts violently with metals. It is used in many industries like glass manufacturing, fertilizer production, chemical synthesis, and metallurgy. Calcium sulfate is a compound containing calcium ions and oxygen atoms. It is a white powder. It is insoluble in water. It is used in various industries like construction, ceramics, mining, and agriculture.

## Equation 1

$$\ce{CaNO32 \cdot 4H2O -> CaOH2 + 2NaNO3 + 8H2O}$$ $$\ce{2NaHSO4 + 3CaNO3~2 \cdot 4 H2O -> Na2SO4 + CaOH2 \cdot 2H2O + 6H2O}$$

## Trisodium citrate + calcium chloride —> tricalcium dicitrate + sodium chloride

1 $\ce{CaNO32 \cdot 4H20 -> CaOH2 + 2NaNO_3 + 8H20}$ 2 $\ce{2NaHS04 + 3CaNO3_2 \cdot 4h20 -> Na2S04 + CaOH2 \cdot 2h20 + 6H2O }$ 3 $\ce{CaCl2 + Na2SO4 -> CaSO4 + NaCl}$ 4 $\ce{CaSO4 + NaCl -> CaCl2 + Na2S04}$ 5 $\ce{CaCO3 + Na2S04 -> CaSO4 + CO2}$ 6 $\ce{CaC02 + Na2S04 + H2O -> CaSO4 + C02 + 2Na2S04}$

## What happens when you mix sodium hydroxide and citric acid?

Sodium hydroxide NaOH is a base that dissolves in water forming a solution. It is used in many industrial processes such as making soap and glass. Sodium hydroxide is also used in household products such as dishwashing detergents and laundry detergent. When you mix sodium hydroxides and citric acids, the following reaction occurs. 2NaOH + 2Citric Acid → 2NaCitrate + H2O

## How do you make citric acid crystals at home?

Hydrochloric acid HCl is a very strong acid that can react with sodium hydroxide to form sodium chloride common salt. Hydrochloric acid is used in many chemical reactions, especially in the production of chlorine gas. What happens when sodium hydroxides reacts with citric acid? Answer: Citric acid is an organic compound that contains two carboxylic groups -COOH and a single hydroxyl group -OH. In acidic solution, these functional groups are ionized into -COO− and -OH− ions. These ions combine to form a salt called citrate.

## What is the best way to get citric acid?

Sodium hydroxide NaOH is a strong base that can react with acids to produce salts. It’s used in many industrial processes such as making glass, soap, detergents, and paper products. Sodium hydroxide is also used in medicine as a laxative and antiseptic. How does sodium hydroxide react with citric acid? Answer: Citric acid is a weak acid that dissolves easily in water. It’s found naturally in citrus fruits and other plants. Citric acid is used in many industries, including food processing and pharmaceuticals.

## When hydrochloric acid reacts with sodium hydroxide in a test tube what will happen?

If you want to make a reaction to citrate, you can mix equal parts of sodium bicarbonate baking soda and citric acid. This mixture reacts to form carbon dioxide gas, which is what gives baking soda its characteristic fizz. You can also mix citric acid with baking soda to make a chemical reaction that produces hydrogen peroxide. Hydrogen peroxide is a powerful disinfectant that kills bacteria and viruses.

## What happens when sodium hydroxide reacts with acid?

To extract pure citric acid from citrus fruits, you can simply squeeze the fruit juice into a clean glass jar and let it sit overnight. Citric acid is a natural preservative found in many fruits and vegetables. It helps prevent spoilage and extends shelf life. Citric acid is used in a wide range of products such as mouthwash, toothpaste, deodorants, shampoos, conditioners, hair color, skin care products, cosmetics, and pharmaceuticals.

## How do you extract pure citric acid?

To get citric acid crystals, follow these steps: 1. Mix 1 cup of citric powder with 2 cups of water. 2. Add 5 drops of essential oils eucalyptus, lemon, orange and mix well.

## How do you make a reaction to citric acid?

Citric acid is a natural compound found in citrus fruits. It is used in many industries such as food processing, pharmaceuticals, cosmetics, and even in the production of plastics. Citric acid is usually produced from fermentation processes using microorganisms. However, if you want to produce citric acid yourself, you can buy citric acid crystals online. To make citric acid crystals, you will need citric acid powder, distilled water, and a glass jar. Put 1 cup of citric acid powder into the glass jar and fill it with distilled water until the jar is half full. Close the lid tightly and shake the jar vigorously. Leave it undisturbed for 24 hours. After 24 hours, filter the mixture through cheesecloth and discard the liquid. Keep the citric acid crystals in a dry place.
