What is the value of [oh–] in a 0.820 m solution of sr(oh)2?

1 answer:

4 0

Strontium Hydroxide Ionizes as follow,

Sr(OH)₂ → Sr²⁺ + 2 OH⁻
So,
1 mole of Sr(OH)₂ produces 2 moles of Hydroxides,

If the concentration of 1 M Sr(OH)₂ produces 2 M OH⁻ ions then, 0.082 M Sr(OH)₂ will produce,

[OH⁻] = 2 × 0.082

[OH⁻] = 0.164 M
