Question

Two acids 'A' and 'B' were kept in beakers. Acid 'A' undergoes partial dissociation in water, whereas acid 'B' undergoes complete dissociation in water.
i) Of the two acids 'A' and 'B', which is weak acid and which is strong acid?
ii) What is a weak acid?
iii) What is a strong acid?
iv) Give one example of each.

Answer 1

$\left(ii\right)$ Weak acid doesn't dissociate completely in water.

$\left(iii\right)$ Strong acid dissociate in water completely and rapidly.

$\left(i\right)$ So, $A\to$ Weak acid

$B\to$ Strong acid

$\left(iv\right)$ Weak acid $\to$ Acetic acid

Strong acid $\to$ Sulphuric acid
