2. Answer the following in one sentence :
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.
