Question

Which of the following is a strong acid? (a) Nitric acid (b) Citric acid (c) Acetic acid (d) Tartaric acid

Answer 1

Answer :

Nitric acid

Explanation :

• Strong Acids :

The acid that completely ionise in the aqueous solution is called a strong acid . The lesser the pH value of an acid , strong will be its acidic character . A strong acid releases more $\tt{H^+}$ when dissolved in water .

These acids are also called mineral acids as they are formed from the minerals from the earth . Some common examples of strong acids are : Hydrochloric acid (HCl ) , Sulphuric acid $\tt H_2SO_4$ , Nitric Acid $\tt HNO_3$ , etc .

• Weak Acids :

The acids which do not ionise completely in aqueous solution and give less $\tt H^+$ ions are called weak acids . These acids have high pH value and are mostly eatable .

These acids are naturally occurring acids . For example : Citric acid (in citrous fruits) , Tartaric acid (in tamarind) , acidic acid (in vinegar) , formic acid (in ant sting) , etc.
