Question

0.98 g of Potassium is allowed to react completely with water. The resulting solution is diluted to 100 cm ^ 3 Calculate the concentration, in mol d * m ^ - 3 , of the resulting potassium hydroxide solution.

2K (s) +2H 2 O (i) 2KOH (aq) +H 2 O (g)

Answer 1

Explanation:

Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.

Chemical equation:

2K(s)+2H

2

O(l)→2KOH(aq)+H
