2. MgCl2.6H2O on heating gives anhydrous MgCl2. (1982)
3. When PbO2 reacts with a dilute acid, it gives hydrogen peroxide. (1982)
4. Copper metal reduces Fe2+ in an acid medium. (1982)

6. Dilute HCl oxidizes metallic Fe to Fe2+. (1983)
7. In an aqueous solution chlorine is a stronger oxidizing agent than fluorine. (1984)
8. Silver chloride is more soluble in very concentrated sodium chloride solution than in pure water. (1984)
9. Solubility of sodium hydroxide increases with increase in temperature. (1985)
