Write out the balanced equation for the reaction that occurs when mg(oh)2 and hcl react together.

The balanced equation for the reaction that occurs when Mg(OH)2 and HCl react together is:

Mg(OH)2+2HCl >MgCl2+2H20

level 4 to level 2 : ))

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
