What is the pH of the solution containing 2.5 X 104 of OH- at 25°C?

Sodium hypochlorite solution, sold as “chlorine bleach,” ispotentially dangerous because of the basicity of ClO⁻, the active bleaching ingredient. What is [OH⁻] in an aqueous solution that is 6.5% NaClO by mass? What is the pH of the solution? (As-sume d of solution= 1.0 g/mL.)

Calculate the pH of an aqueous solution at 25°C that is 7.4 × 10¬3 M in HI. pH

What is the pH of a sodium hydroxide solution at 25 deg C in which the hydroxide ion concentration is 0.0063 mol/L? Is the solution acidic or basic?

Acetic acid (CH3COOH, ?a=1.80×10−5) is a weak acid, so the salt sodium acetate (CH3COONa) acts as a weak base. Calculate the pH of a 0.493 M solution of sodium acetate.

HClO is a weak acid (?a=4.0×10−8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.076 M in NaClO at 25 °C?

What is the OH- concentration for a solution at 25°C that has a pH of 8.61? At this temperature Kw is equal to 1.0 x 10-14.
