Question 7

Name two metals which will displace hydrogen from dilute acids, and two metals which will not.

Answer

Metals that are present at the top reactivity series are more reactive like potassium and sodium. So hydrogen displaced from dilute acids. Metals that are less reactive than hydrogen do not displace it that are present at the bottom of reactivity series like copper and silver.
