Sodium acetate is a salt of a strong base and a weak acid. The solution will be a weak base. It is soluble in water (70g/100ml). Strong electrolytes are either strong acids or soluble salts. (All compounds containing alkali metal ions, ammonium, nitrate, or acetate ions are soluble).
Strong electrolytes: strong acids, strong bases, salts (soluble)
Strong acids: HCl, HBr, HI, HNO3, HClO3, HClO4, H2SO4
Strong bases: NaOH, KOH, LiOH, Ba(OH)2, Ca(OH)2
Weak electrolytes: weak acids and weak bases
Weak acids: HF, HC2H3O2, H2CO3, H3PO4, others
Weak bases: NH3, pyridine, and other compounds containing nitrogen
