Question

Potassium oxide +water =potassium hydroxideu

Answer 1

Explanation:

KO2 + H2O -> 2KOH

Additional information -

• Potassium Oxide reacts with water to form Potassium Hydroxide.

• Potassium belongs to the Group 1 (Alkali Metals)

• K is a s-block element.

Atomic Number -

• 19

• Density of K is less than 1 g/cm³.

• Oxide and Hydroxide of Alkali Metals are Basic in nature.

• KOH is used in manufacturing of soft soap.

• KOH is also used as an excellent absorbent of CO2.

Molar Mass of K2O -

39 × 2 + 16

= 78 + 16

• = 94 g/mol

Molar Mass of H2O -

1 × 2 + 16

= 2 + 16

• = 18 g/mol

Molar Mass of KOH -

39 + 16 + 1

• = 56 g/mol
