Question

What happens when metal react with base?​

Answer 1

The base has a bitter taste and a slippery texture. A base dissolved in water is called an alkali. When chemically reacting with acids such compounds produce salts. Bases are known to turn blue on red litmus paper.

When a base reacts with a metal, hydrogen gas is produced. It burns with a pop sound when a burning candle is brought near the mouth of the test tube.

Metal + Base → Hydrogen + Salt

Example

Sodium hydroxide as it reacts with zinc metal gives hydrogen gas & sodium zincate.

2 NaOH + Zn → H2 + Na2ZnO2

What happens when metal react with base?

ANSWER ⤵️

Acid reacts with base (alkali) to produce salt with hydrogen gas but in general bases do not react with metals and release hydrogen gas.

example:::-➡

2NaOH +Zn➡➡➡ H2+ Na2ZnO2

(sodium hydroxide as it reacts with zinc metal gives hydrogen gas in sodium zincate).
