What is the pH of the solution obtained by titrating 1.24 g of NaHSO4 dissolved in 50mL of water with 0.175 sodium hydroxide until the equivalence point is reached? Assume that any volume change due to adding the NaHSO4 or to mixing the solutions is negligible. The answer says it's 7.47, but I'm unsure how.
