Statement II : Potassium metal reacts violently with water to form potassium hydroxide and hydrogen gas.
Select the correct answer from the options given below :

Options

A. Statement I is true, Statement II is false.
B. Statements I is false, Statement II is true
C. Both Statements are true and Statements II provides explanations to Statements I.
D. Both Statements are true but Statement II does not Provides explanation to Statement I.

Answer

D

Explanation

Sodium metal reacts violently with water because it is extremely reactive than hydrogen. When sodium is put into water they are highly reducing agent, hence they react with water of form their hydroxide. Also the density of sodium is low, It floats on water. It reacts with `H_(2)O` to form hydroxide.
`2Na(s) + H_(2)O(l) to 2NaOH + H_(2) (g)` + Heat energy Metals like Na, K , Ca, Mg etc. react with water to produce metal oxide and hydrogen gas. Potassium is more reactive/electropositive than sodium. Potassium has a lower melting point and ionization enthalpy. Hence molten metal spread and violently react with water.
`2K(s) + H_(2)O(l) to 2KOH + H_(2) (g) +` Heat energy
