Given two solutions 0.10m hcl and 0.10 hf, which solution has the greater concentration of h+ ions? calculate ph values for the two solutions given that [h+] = 7.9 x 10-3m in the 0.10m hf

1) HCl has the greater concentration of H⁺ ions than HF.

2) pH of HCl = 1.

pH of HF = 2.1.

Explanation:

1) which solution has the greater concentration of H+ ions?

HCl is completely ionized in the solution to produce H⁺ and Cl⁻.

∴ 0.1 M HCl has H⁺ concentration of (0.1 M).

0.1 M of HF has H⁺ concentration of (7.9 x 10⁻³ M).

∴ HCl has the greater concentration of H⁺ ions than HF.

2) Calculate pH values for the two solutions:

∵ pH = - log[H⁺]

[H⁺] = 0.1 M.

∵ pH = - log[H⁺]

∴ pH = - log[H⁺] = - log(0.1 M) = 1.

[H⁺] = 7.9 x 10⁻³ M.

∵ pH = - log[H⁺]

∴ pH = - log[H⁺] = - log(7.9 x 10⁻³ M) = 2.1.
