## What volume of 0.100 M NaOH is required to precipitate all of the nickel(II) ions from 150.0 mL of a 0.249-M solution of Ni(NO3)2?

Interpretation Introduction

Interpretation: The required volume of 0.100MNaOH has to be calculated.

Concept Introduction:  The precipitate will be formed when two soluble salt solutions combined together is called as a precipitation reaction.

Ni2++2OH-Ni(OH)2(s)

Alternatively

Ni(NO3)2(aq)+2NaOH(aq)Ni(OH)2(s)+2NaNO3(aq)

Ni(NO3)2 is treated with sodium hydroxide to give nickel hydroxide and two moles sodium nitrate.

Formula:

Mole=volumeofsolution (L)×molarity (M)litre (L) (1)

### Explanation of Solution

Explanation

Substitute volume and Molarity of Ni(NO3)2 in formula (1) we get the mole of solutions. Ni(NO3)2(aq)+2NaOH(aq)Ni(OH)2(s)+2NaNO3(aq)

Ni(NO3)2 is treated with sodium hydroxide to give nickel hydroxide and two moles sodium nitrate.

Mole=volumeofsolution (L)×molarity (M)litre (L) (1)

Substitute the volume and molarity of solution in mole formula (1) to get moles of Ni(NO3)2 we need a stoichiometrically balanced equation to inform our calculation

Given:

Volume = 150ml =150/1000 , 150mlis dividedby 1000

We get L =0.150L

Molarity = 0.249M

= 0.150(L)×0.249(M)1(L)

molarity 0.249(M) is multiply by 0.150L to give 0.03735 then this value divided by 1 we get

Mole of Ni(NO3)2 solution = 0
