HCl is a strong electrolyte. A bottle of HCl contains the label 0.015 M HCl(aq). Which statement concerning this HCl solution is FALSE? A. The solution is acidic. B. The pH of the solution is 1.5. C. The hydronium ion concentration in this solution is 0.015 M. D. The solution has a higher concentration of hydronium ions than hydroxide ions. E. The solution contains dissolved H3O* and Cl ions only: no HCl molecules are present.

Respuesta :

The calculated pH of the given solution 0.015M HCl (aq) is equal to 1.82. Therefore, option (A) is a FALSE statement concerning this HCl solution.

What is pH?

The pH of a given solution can be defined as the negative logarithm of hydrogen (H⁺) or hydronium ion concentration. Mathematically, pH is inversely proportional to the concentration of (H⁺) ions.

pH = -log ([H⁺])

In chemistry, pH scale is used to calculate the acidic or basic strength of an aqueous solution. The pH scale exhibits a range from 0 to 14. A low pH (about 1 or 2) is acidic while a pH of 7.0 is neutral and a high pH (12 or 14) is basic.

Given the concentration of HCl aqueous solution= 0.015M

The hydronium ion concentration, [H₃O⁺] = 0.015 M

pH = -log [H₃O⁺] = - log (0.015)

pH = 1.82

As the HCl is strong acid it will completely dissociate and no HCl molecules are left in the solution.
