WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, Kw, with temperature. At 25°C we know it to be 1.0 x 10^(-14), but at something like 50°C it's about 5.5 x 10^(-14). WebA 1 M solution of H 2 SO 4 will contain one mole of H 2 SO 4 in 1 liter of solution, but if the solution is titrated with a base, it will be shown to contain two moles of acid. This is because a single molecule of H 2 SO 4 contains two acidic protons (H+ Ions). Thus, a 1 M solution of H 2 SO 4 will be 2 N. The normality of a solution is the ...
