Consider a titration of 20.00mL cyanic acid solution (Ka=3.5x10^-4) with 0.1082 M solution of sodium hydroxide. The volume of 21.70 mL of NaOH(aq) was needed to reach the equivalence point. Calculate:a) the concentration of the cyanic acid solution before the titrationb) the pH of the cyanic acid solution before the titrationc) the pH of the solution at half-equivalence point
