A bottle is marked with acid pH = 5, whether the acid is strong or weak? Explain.

Acetic acid is a weak acid because

State on what basis are acids, bases and salts classified as strong or weak electrolytes .

The extent to which hydrolysis proceeds is expressed as degree of hydrolysis and is defined as fraction of ne mole of the salt that is hydrolysed when equilibrium has been attained . The nature of solution also depends upon the extent upto which the salt has been hydrolysed . Degree of hydrolysis of a salt ofdepends upon concentration of salt at a particular temperature and varies inversely . Consequently , nature of the solution whether acidic or alkaline can be determined . pH of the solution of salt of weak acid and strong base or weak base and strong acid depends upon its concentration . So by varying the concentration of salts their pH could be adjusted . For strong acid and weak base salt solution , the [H_(3)O^(+)] at equilibrium will be

pH of acid rain is sometimes as low as 2. Explain.

The graph represents the titration curve for : a.Strong acid and strong base b.Strong acid and weak base c.Weak acid and strong base d.Weak acid and weak base

What are strong and weak acids? In the following list of acids separate strong acids from weak acids . Hydrochloric acid, citric acid , acetic acid, nitric acid formic acid , suphuric acid.

Assertion: The pH of a buffer solution does not change appreciably on additions of a small amount of an acid or a base. Reason: A buffer solution consists of either a weak acid and its salt with a strong base or a weak base its salt with a strong acid.
