What volume (mL) of 0.1044 M NaOH is required to fully titrate (to the second equivalence point ) the amount of glycine hydrochloride?
How will you prepare 10 mL of 0.050 M HCl from a 0.10 M solution of HCl? Assume that you use a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL).
If you dilute 750.00 mL of a 4.117 × 10-4 M solution into a 2.00 L volumetric flask and fill to the line with water, what would be the final concentration of the solution?
How many moles of Cr(OH)3 will dissolve in 1.00 L of a solution with a pH of 5.13. (Assume the pH does not change as the Cr(OH)3 is placed in the water.) (Ksp for Cr(OH)3 is 6.7 x 10-31)
