Salt Solution

Postby Courtney McHargue 1I » Mon Jan 21, 2019 7:15 pm

When you're calculating the pH of a salt solution do you always ignore the ions that don't take part in the reaction and dissolve away?

Yes, these ions are spectator ions and will not change the pH because they are stable as ions and do not donate or pull protons to or from the solution

Yes, if they're just asking you to calculate the pH and there's an ion that does not take part in the reaction, then you always ignore that ion because it won't affect the pH.

Spectator ions are ions that are present in a solution but don't take part in a solution's chemical reaction. When reactants dissociate into ions, some of the ions may combine to form a new compound. Therefore, because they don't take on the role of an electron donator or acceptor, they will not affect the pH of the solution and can be ignored.

how are we able to tell if the acid or base is weak or strong when a salt is present in the reaction?

would any compound solids and liquids just be considered spectators in the reaction as well?
