Solution: Identify each of the following substances as strong electrolyte, weak electrolyte, or nonelectrolyte:A) Ba(NO3)2,B) Ne,C) NH3,D) NaOH,

Solution: Identify each of the following substances as strong electrolyte, weak electrolyte, or nonelectrolyte:A) Ba(NO3)2,B) Ne,C) NH3,D) NaOH,

Problem

Identify each of the following substances as strong electrolyte, weak electrolyte, or nonelectrolyte:

A) Ba(NO3)2,

B) Ne,

C) NH3,

D) NaOH,

Solution

We’re being asked to classify each given compound as a strong electrolyte, weak electrolyte, or nonelectrolytes. Recall that:


• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases

a. Ionic salts: those that follow the rules of being soluble in solubility rules

b. Strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, HClO3

c. Strong bases: Group 1A and 2A (Ca and lower) metals paired with OH, H, O2–, or NH2


• Weak electrolytes: doesn’t dissociate completely in water; include weak acids and bases

a. Weak acids: include HF, HC2H3O2, HNO2, H2CO3, H3PO4

b. Weak bases: Be(OH)2, Mg(OH)2, NH3, NH4OH


• Nonelectrolytes: doesn’t dissociate at all; include molecular compounds

a. Alcohols: composed of carbon and hydrogen with a –OH group

b. Sugars: for example C6H12O6 (glucose) and C12H22O11 (sucrose)

c. Water (H2O)
