1) There is a aqueous solution that has 0.15M and a monoprotic acid that is 3.85. Calculate Ka and state if the acid is WEAK or STRONG.
2) The pKa of hydrogen cyanide is 9.21. In a 100mL solution there are 0.30M of hydrogen cyanide and 0.50M sodium cyanide, there is 0.0050 moles of solid sodium cyanide without changing the volume. Find the resulting pH of the solution.
3) Why would a monoprotic acid that is neutralized not always be neutral?
