Calculate the pH of a \(0.01\,M\) \(HCl\) solution.

A saturated solution of \( H_2S \) in 0.1M HCl at 25°C contains \( S^{2-} \) ion concentration of \( 10^{-23} \, \text{mol L}^{-1} \). The solubility product of some sulfides are \( CuS = 10^{-44} \), \( FeS = 10^{-14} \), and \( MnS = 10^{-25} \). If 0.01M solution of these salts in 1M HCl are saturated with \( H_2S \), which of these will be precipitated?

Calculate pH of a buffer prepared by adding 10 mL of 0.10 M acetic acid to 20 mL of 1 M sodium acetate [\( \text{CH}_3\text{COOH} \)] at \( \text{pH} = 4.74 \).

20 mL of 2.0 M NaOH is added to 50 mL of 0.2 M HCl. The pH of this solution after mixing is:
