a Use the rules for logarithms and exponents to solve for [H*] in terms of pH. [H*] = |10PH b If pH = 9.15 then [H*] =C |M

Begin from total differential equation (Exact DE). Substitute the measurable or P, T,V terms to nonmeasurable or the U, H,G,A,S terms. derive this equation: to: dH = H = H (T, P) (3FF) ƏT (OP) dF dP ӘР T dT + + + [V - Tor] ]d² dP dH = CpdT + V-T
