PART A)

A solution is prepared by mixing equal volumes of 0.17 M HCl and 0.42 M HNO3. (Assume that volumes are additive.) Express the pH to two decimal places.

PART B)

Using the chart Estimate [H3O+] in a 1.5 M solution of each acid.

Express the molar concentrations to two significant figures separated by commas.

I'm stuck on the one that says very large. For all the other ones I multiplied the Ka by the 1.5M. The answer for the large one is NOT "verylarge" 1.5 or 0. Please help!

Acid Formula Ka
Formic HCO2H 1.8×10−4
Hydrocyanic HCN 4.9×10−10
Perchloric HClO4 very large
Hypobromous HOBr

2.0×10−9
