Answer :
Answer:
0.246M
Explanation:
0.123M x 2 = 0.246M
Due to Sr(OH)2 has the coefficient of 2.
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C is 0.246M
What is Concentration ?
The amount of a solution's solute to either the solvent or the entire solution is called Concentration.
The most common way to express concentration is in terms of mass per unit volume.
The solute concentration, on the other hand, can be expressed in moles or units of volume.
We assume
Sr(OH)2 is a strong base, such that
Sr(OH)₂(s) + H₂O(l) −−−→Sr²⁺(aq)+2OH⁻aq)
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C
= 2 * 0.123
= 0.246 M
As two [OH⁻] are being produced by Sr(OH)₂ .
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C is 0.246M.
