Question

when a drop of dil.sulphuric acid is put on a ph paper the color observed is not the same as when a drop of vinegar (dilute acid) is put on it explain

Answer 1

Answer:

Dil. Sulphuric Acid is is a strong acid whereas a drop of vinegar is a weak acid.

A strong acid produces more number of H+ ions whereas is a weak acid produces less number of H+ ions.

This is the reason a drop of dilute sulphuric acid on the pH paper, the colour observed is not the same as the the colour produced when a drop of vinegar is on the pH paper.

More information:-

• The acidic nature of a substance is because of the formation of H+(aq) ions.

• The basic nature of a substance is because of the formation of OH-(aq) ions.

• Thestrength whether the acid or the alkali is strong or weak is tested using scale called the pH scale.

• It is a scale from 0 to 14 which gives the measure of concentration of hydrogen ions.

• When the pH is around 7, the solution is said to be neutral.

• When the pH is less than 7 that is between 1 to 7, the solution is said to be an acid.

• When the pH is more than 7 that is between 7 to 14, the solution is said to be a base.

Answer 2

Answer: there is more no of *H+* ions in *Dilute Sulphuric Acid* but there vinegar produce less H+ ions compared to dilute H2SO4 . So vinegar is weak than H2SO4.
