What is the molarity of 2.00 L NaOH Solution prepared from the dilution of 50.00 mL of 19.1 M NaOH?
A buffer that has .370 m base and .234 m of its conjugate acid contain ph of 9.09. what is the ph after .002 mol of HCL is added to .250 l of this solution.
Compute the pH of the titration solution before any acid is added, when the titration is 1.00 mL short of the equivalence point, when the titration is at the equivalence point, and when the titration is 1.00 mL past the equivalence point.
