Because sodium and potassium are very reactive metals so they react explosively with HCL and H2SO4 evolving a large amount of heat....

Potassium, sodium, lithium and calcium all react violently
with dilute sulfuric acid and dilute hydrochloric acid.
It is dangerous to put thesemetals into an acid.
The reaction is similar to the reaction with water,
forming the metal salt (either sulfate or chloride) plus H2(g).
