Question

The picture size is too big so I will just have to type it out.

The question states: Decide whether each of the following is a strong acid, weak acid, strong base, weak base, or neutral base. Then decide whether it would be classified as a strong electrolyte, weak electrolyte, or non electrolyte. Hint: two are acids, two are bases, and two are neutral. There are three strong electrolytes, two weak electolytes and one non electrolyte.

Here are the substances:

KBr

HCHO₂

LiOH

CH₃OH

HBr

NH₃

I'm not sure where to even begin with this, not sure how to determine what it is asking. Also not sure if this would be considered multiple questions.

Answer 1

KBr - Neutral , Strong electrolyte

HCHO2 - Weak acid , weak electrolyte

LiOH - strong base, strong electrolyte

CH3OH - Neutral , Non electrolyte

HBr - Strong acid, Strong electrolyte

NH3 - weak base , weak electrolyte

Explanation

1)An acid is Weak or strong is determined by how much H+ ions it giving on dissociation

HA <--------> H+ + A-

Ka = [H+][A-]/[HA]

Weak or strong base is determined by how much OH- it giving on dissociation

B + H2O <------> BH+ + OH-

Kb = [BH+][OH-]/[B]

2) 100% ionizings are Strong electrolyte

partly dissociatings are weak electrolyte

No dissociatiings are non electrolyte
