The general rule is that when a metal and an acid react, they produce a salt and hydrogen gas. For example: Magnesium + Hydrochloric Acid --> Magnesium Chloride + Hydrogen Sodium + Hydrochloric Acid --> Sodium Chloride + Hydrogen
Zinc + Hydrochloric acid is a basic metal acid reaction. When the Zinc is added to the acid, the zinc dissolves and reacts with the acid, forming hydrogen gas and the salt Zinc Chloride. These sorts of reactions (metal +… Full Answer
Zinc metal reacts vigorously with hydrochloric acid forming effervescence or gas bubbles of hydrogen gas and aqueous zinc chloride. The reaction is exothermic and temperature of the reaction mixture increases.
Pheniphthalein turns pink in basic medium. If the solution with containing phenolphthalein is basic, the pink color of the solution decreases when hydrochloric acid is added. If the solution is acidic, no color change will occur.
