Question

distinguish between acids and bases. physical and chemical properties plzz

Answer 1

heya..

here is ur ans..

ACID-
1) acids are sour in taste

2) it turns blue litmus into red

3) all the acids react with metals

4) the pH value of acid is between 0 -7

5) for ex.Hydrochloric acid(HCl)


BASES-

1) they are bitter in taste

2) it turns red litmus into blue

3)all the bases do not react with metals

4)the pH value of bases is between 7-14

5) for ex. sodium hydroxide (NaOH)

hope helped..

Answer 2

Hey....

difference between acid and base on the basis of physical properties:-

ACID:--

*acids are sour in taste.

*Acid turns blue litmus to red.

*Strong acids damaged the fabrics.

*Acids are electrolytes..

BASE:--

*Bases are bitter in taste.

*Bases turns red litmus to blue.

* It is soapy to touch .

*it turns colorless phanephthaline to pink.....

Now... difference between acid and base on the basis of chemical properties:-

ACID:--

*when acid reacts with metal it forms salt and water.
eg. HCl +Na--->Nacl+H2O...

*When acid reacts with carbonate then it forms salt , water and CO2..
eg...MgCO3 +Hcl----->MgCl2+H2O+CO2....

*when acid reacts with base it will form salt and H2O and it is also called neutralization reaction..
eg....HCl+NaOH------->NaCl+H2O..

BASE:----

*when base reacts with metal it forms salt and hydrogen gas..

*when base reacts with salt.
eg...2 NH4Cl+Ca(OH)2---->CaCl2 +2NH3+2H2O.......



Hope this will help u...
