Answer:

Answer

5. Strong electrolytes are the strong acids, strong bases, and salts. These are completely dissociate into ions in aqueous solution.

in this question strong electrolytes are – HBr , HNO3. AgNO3.

6. Weak electrolytes only partially break into ions in water. Weak electrolytes include weak acids, weak bases, and a variety of other compounds. Most compounds that contain nitrogen are weak electrolytes.

in this question – HF, NH3

7. for NaI = Na+ and I. for K2SO4 = 2K+ + SO42-  for NaCN = Na+ + CN for Ba(OH)2 = Ba2+ + 2OH.

for (NH4)2SO4 = 2(NH4)+ and (SO4)2-

8. K2SO4 + Ca(NO3)2 = 2 KNO3 + CaSO4

HBr + NaOH = NaBr + H20
