Asolution is prepared by mixing equal volumes of 0.16 m hcl and 0.52 m hno3. (assume that volumes are additive.)

express the ph to two decimal places.

The pH of the final solution is 0.16 .

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ion concentration in a solution.

Concentration of HCl = 0.16 M

HCl is a string acid .1 molar of HCl gives 1 molar of of hydrogen ions.

Concentration of = 0.52 M

Nitric is a string acid .1 molar of nitric acid gives 1 molar of of hydrogen ions.

Total hydrogen ion concentration:

=0.16 M+0.52 M=0.68 M

The pH of the solution:

pH = 0.16

The pH of the final solution is 0.16 .

i think it's letter a.
