Hw Problem 6D.11

[Qilan Li 4I]

For 6D.11, I understand that the ions in the salt would indicate whether the pH will be less or more than 7 (or neutral). However, I used the charts in the textbook to see whether they are ions from strong/weak acids or bases. Do you memorize the different cations and anions for the final? Does anyone have any tips or guides?

[asannajust_1J]

you should know the strong acids and bases, so you will know that everything else would be weak.

[Baoying Li 1B]

Memorize all the strong acids and weak strong. Others will be weak acids and weak bases.

[Debora Fernandez Clemente_ 4H]

what is the complete list of strong acids?

[Jordan Ziegler 2J]

A good acronym for remembering all of the strong acids is B I C P E N S
- B --> HBr (hydrobromic acid)
- I --> HI (hydroiodic acid)
- C --> HCl (hydrochloric acid)
- P E --> HClO4 (perchloric acid)
- N --> HNO3 (nitric acid)
- S --> H2SO4 (sulfuric acid)
