Question
1) Reaction of acids with metals: Drop a small piece of "mossy zinc" into one well with hydrochloric acid and into another well with Acetic acid. Record your observations Observation In which acid does the reaction occur more vigorously? 2) Reaction of acids with carbonates: In a clean test tube put approximately 1 ml of 1 M HCI (From the side bench). In another test tube put approximately 1 ml of 1 M acetic acid (From the side bench). To each tube a small (about a match head size) amount of solid sodium carbonate powder. Observation In which acid does the reaction occur more vigorously?Explanation / Answer
Ans 1 :
Observations :
Zinc reacts with acetic acid to form zinc acetate and hydrogen gas is evolved. It also reacts with HCl to form ZnCl2 and hydrogen gas.
Since Zinc is metal , which is more reactive than hydrogen , it will react with both acetic acid and HCl acid to liberate hydrogen gas. but since HCl is a stronger acid , the reaction occurs more vigourously.
