Is benzoic acid react with sodium bicarbonate?
Yes, benzoic acid will react with sodium bicarbonate to produce sodium benzoate, carbon dioxide, and water. This reaction can be used to extract benzoic acid from a mixture as it is relatively insoluble in water but soluble in sodium bicarbonate solution.
Does chlorine gas react with cold water?
Yes. Chlorine gas reacts with water to give hypochlorous acid and hydrochloric acid Cl2 + H2O -> HOCl + HCl The hypochlorous acid is the "disinfectant" most effective at pH 5, at low pH it forms hypochlorite ions. Remember if the water is impure the chlorine can potentially react with the impurities.
Which substance is produced when chlorine is added to water?
When chlorine is added to water, it can react to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). Hypochlorous acid is the primary disinfectant that helps kill bacteria and other pathogens in water, while hydrochloric acid can contribute to lower the pH of the water.
Is benzoic acid or sucrose more soluble in water?
Sucrose is more soluble in water than benzoic acid. Sucrose is a polar molecule that can form hydrogen bonds with water molecules, increasing its solubility. Benzoic acid, while also polar, has a benzene ring which reduces its ability to form hydrogen bonds with water, making it less soluble.
How can hypochlorous acid be made from salt?
Hypochlorous acid can be made from salt by mixing salt (sodium chloride) with water and passing an electric current through the solution in a process called electrolysis. This causes the salt to break down into its components, sodium and chloride ions. The chloride ions then react with water to form hypochlorous acid.

Benzoic acid plus NaOH plus iodine?
C6H5COOH + NaOH + I2 -----------> C6H5COOI + NaI + H2O
Why is benzoic acid insoluble in water at room temperature?
Benzoic acid is insoluble in water at room temperature because it is a non-polar compound with a long hydrophobic carbon chain that does not interact well with the polar water molecules. This lack of interaction prevents benzoic acid from dissolving in water and results in poor solubility.
What is the minimum amount of water in which 1 g of benzoic acid can be dissolved?
This depends on the temperature; at 25 oC the volume of water is 300 mL.
How much water should be used for the recrystallisation of benzoic acid?
depends on how much benzoic acid you use. if you have 0.5g of benzoic acid , you need 30ml of water as a solvent.
Will chlorine float or sink in water?
Chlorine gas is denser than air and will sink in water. Once in water, it will react to form various compounds, such as hypochlorous acid and hypochlorite ions.
Is chloride a acid or not?
The chloride ion is neither acidic nor basic. Elemental chlorine itself is not acidic, but it will react with water to form hydrochloric acid and hypochlorous acid.
How do you separate benzoic acid from a mixture of benzoic acid and toluene using extraction?
Make a solution of Sodium Hydroxide or Sodium Carbonate and do three to four solvent solvent extractions using the aqueous base and the mixture o benzoic acid and toluene. Because benzoic acid reacts with base to form the water soluble carboxylate ion, it will react and the dissolve in the aqueous solution. Upon separation of the two phases acidify the aqueous extract with dilute HCl, a white needle-like precipitate of benzoic acid will form when the solution becomes acidic. Simply filter the crystals, wash with cold water, and then recrystallize using a mixture of 50/50 water and methanol or some other suitable solvent.
