0.50 g of hydrogen chloride (HCl) is dissolved in water to make 4.0 L of solution. What is the pH of the resulting hydrochloric acid solution

Explanation:

Given the mass of HCl is ---- 0.50 g

The volume of solution is --- 4.0 L

To determine the pH of the resulting solution, follow the below-shown procedure:

1. Calculate the number of moles of HCl given by using the formula:

2. Calculate the molarity of HCl.

3. Calculate pH of the solution using the formula:

Since HCl is a strong acid, it undergoes complete ionization when dissolved in water.

Thus,

Calculation:

1. Number of moles of HCl given:

2. Concentration of HCl:

3. pH of the solution:

Hence, pH of the given solution is 2.47.

beta decay is the answer
