A 4.36-g sample of an unknown alkali metal hydroxide is dissolved in 100.0 ml of water. An acid-base indicator is added and the resulting solution is titrated with 2.50 mL of HCl (aq) solution. The indicator changes color signaling that the equivalence point has been reached after 17.0 ml of the hydrochloric acid solution has been added.

Determine the pH of each two-component solution. d. 0.088 M HClO₄ and 0.022 M KOH

A 40.0 mL sample of a mixture of HCl and H₃PO₄ was titrated with 0.100 M NaOH. The first equivalence point was reached after 88.0 mL of base, and the second equivalence point was reached after 126.4 mL of base. (c) What percent of the HCl is neutralized at the first equivalence point?

A solution prepared by mixing 10 mL of 1 M HCl and 10 mL of 1.2 M NaOH has a ph of
