strong acids and bases

Postby Ruiting Jia 4D » Sat Jan 19, 2019 1:40 pm

Can someone give a quick refresher on how to identify strong acids and bases vs weak acids and bases, and are there pages in the textbook to also help with this? I understand how the two differ when it comes to dissociating in the chemical equations.

The strong acids and bases can be found on F83 in the 6th edition textbook:

Strong acids: HBr, HCl, HI, HNO3, NClO4, HClO3, H2SO4
Strong bases: Group 1 hydroxides, alkaline earth metal hydroxides (Ca(OH)2, Sr(OH)2, Ba(OH)2), Group 1 and Group 2 oxides

If you are given a K value, an acid with a Ka < or a base with Kb less than that value will be a weak acid/base respectively.
(This is also a general rule but works in the majority of situations)
