Strong Acids & Bases Ions

Postby Ariel Fern 2B » Sun Jan 19, 2020 9:21 pm

Can someone give me a refresher of how to identify strong acids & bases and the conjugate ions to look out for in salts based on these? Thanks!

Strong acids and bases are just things you're going to have to memorize. Generally, strong bases are group 1 and group 2 metals with an OH group, meaning their conjugate ions are the metals. Strong acids are HBr, HCl, HI, HNO3, HClO4, HSO4, and their conjugate ions would just be those without the H.

If there is a strong acid, then the conjugate base will be weaker. Similarly if you are presented with a weak acid, then the conjugate base will be stronger. This trend is also true when evaluating the conjugate bases of weak/strong acids.

In terms of identifying strong acids/bases, I would honestly just memorize them as there are around 7 each, and just know that they dissociate completely in water.
