Compute the pH of the subsequent solutions. In every case ignore the effects of ionic strength as well as assume that a(i)=c(i)
(a) 1*10^3 M HNO3
(b) 1*10^4 M KOH
(c) 5*10^8 M HCl (careful; this not as easy as it looks)
(d) Accurate the results in the problem for the effects of ionic strength and compare the results
