When liquid phosphorus trichloride is added to water, it reacts to form aqueous phosphorous acid, h3po3(aq), and aqueous hydrochloric acid?

Respuesta :

Liquid phosphorus trichloride, PCl3, reacts exothermically with water, H2O, in a very fast reaction. The reaction then forms aqueous phosphorous acid, H3PO3(aq) and aqueous hydrochloric acid, HCl(aq).The balanced chemical reaction is as follows: PCl3 + 3 H2O → H3PO3 + 3 HCl. Its product, phosphorous acid, is an important precursor for the manufacture of other phosphorous compounds.

Complete question: When liquid phosphorus trichloride is added to water, it reacts to form aqueous phosphorous acid, h3po3(aq), and aqueous hydrochloric acid. express your answer as a balanced chemical equation. Identify all the phases in your answer?

SOLITION:

The solution to the question we have here is to balance the chemical reaction. But before we do that, let us take some notes on one of the REACTANTS, Phosphorus trichloride. Phosphorus trichloride is also known as trichlorophosphine. Phosphorus trichloride is a yellow fuming liquid that has a pungent smell. The smell of Phosphorus trichloride is very similar to that of Hydrogen chloride.

Phosphorus trichloride has a molecular weight of 137.33 g/mol.

Phosphorus trichloride can react with water to form HP0(OH)2 with HCl or H3PO3 and HCl.

The balanced equations of Reaction are given below;

(1). PCl3 (l)+ 3H2O (l) --------> H3PO3 (aq) + 3HCl (aq).

(2). PCl3 (l) + 3H2O (l) ------> HPO(0H)2 (aq) + 3HCl (aq).

For the question, the reaction to use is the equation (1).

Phosphorus trichloride,PCl3 is in liquid phase, water,H2O is in liquid phase two( both reactants are in liquid phase).

H3PO4 are both in aqeous phase.
