A 35.0 mL sample of 0.150 M acetic acid (HC2H3O2) is titrated with 0.150 M NaOH. Calculate the pH after 34.5 mL of NaOH has been added.
what is the ph of a Solution prepared by mixing 163.0 ml of 2.4×10?3 MHCl and 382.0 ml of 1.4×10?3 HClO4 (Assume that volumes are additive.)
Give specific outline as to how you would prepare the solution by two different methods, one by dilution and one by weighing pure chemical. (Show calculation, what type of glassware is used, include size and kinds of pipets and flasks)
In less than a 150 words, explain why swirling or shaking a solution and its drying agent hastens the drying process.
