Question
Hypothesize which mixtures you think will be able to resist changes in pH upon addition of either acid or base. (Check the appropriate box for each.
Mixture Won’t resist change in pH upon addition of acid or base Will resist change in pH upon addition of acid only Will resist change in pH upon addition of base only Will resist change in pH upon addition of acid and upon addition of base A 0.10 M NaC2H3O2 solution A 0.10 M NaCl solution A 0.10 M NaCl solution A solution that is 0.10 M HC2H3O2 and 0.10 M NaC2H3O2 One part 0.10 M NH3 mixed with one part 0.10 M NH4Cl A solution that is 0.10 M NH3 and 0.20 M NH4Cl Three parts 0.10 M NH3 mixed with one part 0.10 M HC One part 0.10 M NaOH mixed with one part 0.10 M HCl One part 0.10 M NaOH mixed with one part 0.10 M NH4Cl One part 0.10 M NaOH mixed with two parts 0.10 M NH4Cl DI water (just solvent)Explanation / Answer
If the solution is buffer then that will resist change in pH upon addition of acid and upon addition of base.
Some of the given solutions are buffer solution some are not.
