Transcribed text From Image: Which of the following are strong electrolytes: BaSO_4, AgNO_3, HBr, HNO_2 and HC_2H_2O_2 6. Which of the following are weak electrolytes: HNO_3, HF, HI, NH_3(aq) and KOH? 7. For each of the following water-soluble compounds indicate the ions present in an aqueous solution: Nal, K_2SO_4, NaCN, Ba(OH)_2, and (NH_4), SO_4. 8. Write a balanced chemical equation showing how you could prepare each of the following suits from an acid-base reaction: KNO_3, NaBr, and CaS.
Expert Chegg Question 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
