vi. The pH of a solution is 6.06. Calculate its H⊕ ion concentration.

Given: pH of solution = 6.06

To find: \(H^+\) ion concentration

Formula: pH = \(-\log_{10}[H_3O^+]\)

Calculation: From the formula,

pH = \(-\log_{10}[H_3O^+]\)

Therefore, \(\log_{10}[H_3O^+] = -\text{pH}\)

= \(-6.06\)

= \(-6 - 0.06 + 1 - 1\)

= \((-6 - 1) + 1 - 0.06\)

= \(-7 + 0.94\)

= \(-6.06\)

Thus, \([H_3O^+] = \text{Antilog}_{10}[-6.06]\)

= \(8.710 \times 10^{-7}\) M

The \(H^+\) ion concentration of the solution is \(8.710 \times 10^{-7}\) M.
