115. Solving a chemistry problem

What indicator should be taken for titration of 0.18 N. NH4OH solution 0.18 N. hydrochloric acid solution? Plot an appropriate titration curve.
Calculate [H+] and pH for the points when the standard solution 0 is added; 90; 99; 99.9; 100; 100.1; 101.0% of the equivalent amount. Determine the limits of the titration jump and the pH of the medium at the equivalence point. Calculate the indicator titration error for the selected indicator.
