Could someone please explain how to calculate the most likely pH of:
a) 0.20 mol/dm^3 strontium hydroxide?
b) A mixture of 20cm^3 of 1.0 mol/dm^3 nitric acid and 10cm^3 of 1.0 mol/dm^3 sodium hydroxide?
This is from the June 2014 1R paper, questions 4b and 4c. The mark scheme gives the answers as 13.6 and 0.48 respectively.
