Question

pH for a solution of a weak acid

pH for a buffer with equal concentrations of a weak acid and the salt of the weak acid

pH = pKa of a weak acid

pH for a solution of the sodium salt of the weak acid

equivalence point where moles of strong base added is just equivalent to the moles of weak acid in the orignal sample

pH for a solution of strong base and the salt of a weak acid

buffer pH range for the weak acid and its salt

buffer with an excess of the weak acid as compared to the salt of the weak acid

buffer range where the pH of the buffer is less than the pka of the weak acid

buffer pH range with an excess of the salt of the weak acid as compared to the weak acid

buffer range where the pH of he buffer is greater than the pka of the weak acid

Explanation / Answer

A --------> pH for a solution of a weak acid

B ------> pH for a buffer with equal concentrations of a weak acid and the salt of the weak acid

C -------> equivalence point where moles of strong base added is just equivalent to the moles of weak acid in the orignal sample

D ------> pH for a solution of strong base and the salt of a weak acid

E -----> buffer range where the pH of the buffer is less than the pka of the weak acid

F -----> buffer pH range with an excess of the salt of the weak acid as compared to the weak acid
