Here in this problem, given aquas solutions of nickel -2 chloride and sodium carbonate are combined, we have to answer, does a reaction occur or not? and if any reaction occurs, we have to write the balanced net ionic equation.
00:19
First, we'll write the molecular equation.
00:21
Here, nickel -2 chloride, its aqua -solution is combined with the aqua -solution of sodium -carbonate, n -a -2 -co -3.
00:32
And the products are nickel carbonate and sodium chloride.
00:40
Sodium chloride, salt containing group 1 metal like potassium, sodium, sodium, rubidium, cesium, they are soluble according to the solubility rule.
00:51
So this is the soluble salt.
00:53
And nickel carbonate.
00:55
And according to the solubility rule, most of the carbonyts are insoluble, except the carbonates of group one metals, sodium, potassium, rubidium and cesium and so on, and ammonium carbonate.
01:10
They are soluble, but other carbonates are insoluble.
01:14
So here it will be the precipitate.
01:16
Now, in this double displacement reaction, a precipitate is formed.
01:22
So, a reaction occurs.
01:25
Since a precipitate is formed, a reaction does occurs.
01:53
Now we'll write, we have to write the total ionic equation.
01:59
Before that, let's balance it...
