7. A student makes a standard acid by dissolving 4.00 grams of KHSO, to prepare 250 mL of solution.
a. What is the concentration (M) of the standardized acid?
b. The student then uses 45.0 mL of the standard acid to titrate 20.0 mL of NaOH.
What is the concentration (M) of the base?
c. If the base from part (b) was used to titrate 20.0 mL of a 0.32 M HCI. What volume
of base would be required for complete neutralization?
