Why Hcl uses in the preparation of boric acid?
Hydrochloric acid (HCl) is used in the preparation of boric acid because it reacts with borax (sodium borate) to release boric acid. The reaction between hydrochloric acid and borax allows for the precipitation of boric acid, which can then be collected and purified.
What is the balanced equation between borax and hydrochloric acid?
The balanced equation between borax (Na2B4O7·10H2O) and hydrochloric acid (HCl) is: Na2B4O7·10H2O + 2HCl → 4B(OH)3 + 2NaCl + 5H2O
What is the correct equation for reaction between hydrochloric acid and borax?
The correct equation for the reaction between hydrochloric acid (HCl) and borax (Na2B4O7·10H2O) is: 2HCl + Na2B4O7·10H2O -> 4H3BO3 + 2NaCl + 5H2O
Standardization of Hcl using Borax?
You can standardize a hydrochloric acid (HCl) solution using borax (sodium borate) by titrating a known concentration of HCl with a solution of borax. The reaction between HCl and borax can be used to determine the exact concentration of the HCl solution. By accurately measuring the volume of the titrant and using stoichiometry, you can calculate the concentration of the HCl solution.
What happens when borax reacts with hydrochloric acid?
When borax (sodium borate) reacts with hydrochloric acid, it forms boric acid, sodium chloride, and water. The boric acid formed in the reaction is a weak acid and remains in solution. Sodium chloride, a common salt, will precipitate out of the solution.
What is the theory of standardization of hydrochloric acid with Borax?
Borax can be used as a primary standard because it does not decompose in normal storage conditions. The salt will dissociate in water and the anion will be hydrolyzed. This leaves hydroxide ions to be titrated with the hydrochloric acid.

What is the balanced equation for borax and hydrochloric acid?
Na2B4O7.10H2O + 2HCl --> 4H3BO3 + 2NaCl + 5H2O
How do you make borax out of boric acid?
There are five steps on how to make Borax out of Boric Acid. Some of the step-by-step instructions are dilute 25 mm of Hydrochloric Acid with 75 mm of distilled water, put 7g of Borax into a beaker, and then pour in 20 mm of boiling water.
Why would phenolpthalein not be a suitable indicator for the standardisation of hydrochloric acid with Borax?
Phenolphthalein is not suitable for titration involving Borax and hydrochloric acid because it changes color at a pH lower (usually around pH 8-9) than the equivalence point of this specific titration. Borax reacts as a weak base while hydrochloric acid is a strong acid, making the equivalence point acidic in nature. A suitable indicator would need to change color near this acidic pH of the equivalence point.
Is borax an acid?
No, borax is not an acid. It is a salt of boric acid, which has basic properties.
Is borax an acid or a base?
Borax is a base.
Does borax contain boric acid?
Yes, borax contains boric acid.
