Synthesizing citric acid from lemons involves extracting and isolating the citric acid present in the fruit. Here's a simplified overview of the process:

Ingredients :

Fresh lemons (the more, the better)
Water
Sodium Hydroxide ( 11g )
Calcium Chloride ( 10g )
Dilute Sulphuric Acid ( 100ml ) 30%
pH meter (optional for monitoring acidity)
Procedure:

Lemon Selection: Start by selecting fresh, ripe lemons. The quality of the lemons will directly impact the yield and purity of citric acid.

Lemon Juice Extraction: Squeeze the lemons to extract their juice. You can use a juicer or squeeze them by hand. Aim to collect as much juice as possible.

Filtration: To remove any solid particles or pulp from the lemon juice, strain it through a fine filter paper into a large beaker.

Acidity Adjustment (Optional): To ensure the solution's acidity, you can use a pH meter to measure the pH. Citric acid solutions should be acidic, typically with a pH around 2.5. If needed, adjust the pH with small amounts of sodium hydroxide solution.

C6H8O7 (citric acid) + 3NaOH (sodium hydroxide) → 3Na3C6H5O7 (sodium citrate) + 3H2O (water) + 3CO2 (carbon dioxide)

TriCalcium DiCitrate or Calcium Citrate : now add the solution of calcium chloride in the solution and heat it calcium citrate will form. filter the solution to get calcium citrate.

2Na3C6H5O7 (sodium citrate) + 3CaCl2 (calcium chloride) → Ca3(C6H5O7)2 (calcium citrate) + 6NaCl (sodium chloride)

Citric Acid Formation: Now mix the calcium citrate with dilute sulphuric acid to form calcium sulphate and citric acid

Ca3(C6H5O7)2 (calcium citrate) + 3H2SO4 (sulfuric acid) → 3CaSO4 (calcium sulfate) + 2C6H8O7 (citric acid) + 3H2O (water)

Filtration: now filter the solution to remove calcium sulphate and citric acid in the form of solution.

Evaporation: Heat the diluted citric acid solution in the beaker low to medium heat. As the liquid evaporates, citric acid will begin to crystallize. Stir occasionally to prevent burning. Be patient; this process may take several hours.

Crystallization: Once a substantial amount of liquid has evaporated, you will notice citric acid crystals forming. Continue heating until most of the liquid is gone.

Drying: Allow the citric acid crystals to cool and dry. You can place them on a clean surface or a baking sheet. Ensure they are completely dry before storage.

Storage: Store the citric acid crystals in an airtight container in a cool, dry place. It can be used in various applications, such as cooking, cleaning, or as a food preservative.

Purity Check (Optional): If you want to check the purity of your homemade citric acid, you can use a citric acid test kit, following the manufacturer's instructions.

Please note that this process yields homemade citric acid, which may not be as pure or concentrated as commercial citric acid. It's suitable for many culinary and cleaning applications but may not be suitable for pharmaceutical or industrial uses requiring high purity.
