We're being asked to determine a) if an aqueous solution of NaHSO4 acidic, basic, or neutral; b) the reaction occurs with water; and c) calculate the pH of a 0.10-M solution of NaHSO4.
For the first part, NaHSO4 is a salt and will break up in the solution:
NaHSO4(aq) → Na+(aq) + HSO4–(aq)
• Na+ → main group metal → group 1A → +1 charge
▪ less than +3 → neutral
• HSO4– → from the strong acid H2SO4
▪ H2SO4 will completely (100%) ionize in a solution therefore HSO4– will not accept an H+ to reform H2SO4
▪ HSO4– will act as an acid in the solution
Is an aqueous solution of NaHSO 4 acidic, basic, or neutral? What reaction occurs with water? Calculate the pH of a 0.10-M solution of NaHSO4.
