Question

A researcher adds barium hydroxide to hydrochloric acid to form a white-colored barium chloride. Which option gives the balanced chemical equation of the reaction? (0.5)

HCl+Ba(OH)2 -----> BaCl2+2H2O

2HCl+Ba(OH)2 ---->BaCl2+2H2O

2HCl+Ba(OH)2 ----->BaH2+2HCl+O2

HCl+2Ba(OH)à2BaCl2+2HOH+O2

​

Answer 1

Answer:

answer is b option

2HCL +Na(OH)2 =BaCl2+2H2O

Answer 2

The option giving the balanced chemical equation of the reaction is 2HCl+Ba(OH)2 ---->BaCl2+2H2O.

When barium hydroxide is added to hydrochloric acid, a chemical reaction takes place producing barium chloride and water.

$2HCl+Ba(OH_{2})$ →$BaCl_{2} +2H_{2} O$

Let us verify if this equation is balanced or not.

Number of H atoms on LHS = 4 = RHS

Number of chlorine atoms on LHS = 2 = RHS

Number of barium atoms on LHS = 1 = RHS

Number of oxygen atoms on LHS = 2 = RHS

Thus, this equation is a balanced equation.

HCl+Ba(OH)2 -----> BaCl2+2H2O

Here, there is three H-atoms present on LHS while there are four H-atoms on RHS.

There is one chlorine atom on LHS while there are two chlorine atoms on RHS.

2HCl+Ba(OH)2 ----->BaH2+2HCl+O2

During the reaction of barium chloride with hydrochloric acid, barium chloride and water will be formed.
