Question 7a:
Which of the compounds are soluble in water.
Answer is Lithium Chloride and Ammonium hydroxide. Because Lead and Mercury compounds are insoluble in water.
Question 7b:
Which are following water soluble compounds will remain as molecules in solution.
Answer is Glucose and carbon dioxide because these molecules are polar and not salts. Ammonium chloride and magnesium sulphate are salts and dissociated in water.
Question 7c:
Which is completely disseminates into ions in water.
Answer is Barium acetate. Because N2 is gas will not dissociates in water. Lead and Silver compounds are insoluble in water.
