In this question we are assigned to the task to identify the term that appears when aqua solution of aucl3 and cs2 -co3 are mixed.
00:18
Now this is an example of double displacement reaction in which exchange of ions takes place.
00:35
To find out the molecular formula of the products we first determine the charge is on the ketion in the compound and using the principle of charge neutrality we write the formula for the products.
01:00
Once we know the formula of reactant and products we balance the equation by keeping the number of atoms of each element equal on both the sides of the equation.
01:28
Now in case of au -cl -3, the charge on chloride ion is minus 1.
01:35
So we balance the charge, then a -u -c -l -3.
01:39
Must have a charge of plus 3.
01:43
In cs2 -co3, the carburetion has charge of minus 2, therefore cs must have a charge of plus 1.
01:56
The product will thus be formed, au, co3, the charge is plus 3 and minus 2...
