Question

give general reaction and one example for each
(a) acidic reacts with metals
(b) acid reacts with metalic carbonate
(c) base reacts with metal
( d) acid reacts with metalic bicarbonate​

Answer 1

➡(a) Acids react with most metals to form a salt and hydrogen gas. ... For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas.

➡(b) When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing. ... This type of reaction can be used Toyota test unknown solutions to see if they are acidic . ➡ (c) When alkali (base) reacts with metal, it produces salt and hydrogen gas. Example: Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal. Sodium aluminate and hydrogen gas are formed when sodium hydroxide reacts with aluminium metal. ➡(d) Metal carbonates/metal bicarbonates react with acids to produce salt, carbon dioxide and water. For example the reaction of sodium carbonate/sodium bicarbonate with hydrochloric acid . ↪ hope that helps you !!!⛑✒☘❣
