c) For each of the following mixtures, predict whether we can ignore the contribution of the weaker acid to the overall pH (yes or no).

i) 0.010 M nitric acid + 2.0 M chlorous acid

ii) 1.0 M hydrofluoric acid + 0.20 M hydrocyanic acid

iii) 0.30 M hydrofluoric acid + 0.40 M acetic acid

iv) 1.0 M chlorous acid + 1.0 M hydrocyanic acid
