Identifying strong acids and bases

Postby 304922790 » Thu Nov 30, 2017 8:45 pm

What makes an acid or base strong or weak? Do we have to memorize all the weak and strong acids and bases or can we determine which one is weak or strong by drawing the lewis structures?

A strong acid or base is one that disassociates completely in water, such as HCl or NaOH. These acids and bases will be nearly 100% H+ ions and Cl- ions or Na+ and OH- ions respectively. The best way to determine if an acid/base is strong or weak is to memorize them, but there are only 6 strong acids and not too many more strong bases. I will list them below.

Strong Acids:
HCl H2SO4
HBr HClO4
HI HNO3

Strong bases:
LiOH Ca(OH)2
NaOH Sr(OH)2
KOH Ba(OH)2
RbOH
CsOH

What's a binary acid?
