Which of the following gives only 50% moles of AgCl, when reacts with AgNO3 :-PtCl2 · 4NH3PtCl4 · 5NH3PtCl4 · 4NH3PtCl4 · 3NH3
Question
Which of the following gives only 50% moles of AgCl, when reacts with AgNO3 :-PtCl2 · 4NH3PtCl4 · 5NH3PtCl4 · 4NH3PtCl4 · 3NH3
Solution
The compound that gives only 50% moles of AgCl when reacts with AgNO3 is PtCl2 · 4NH3.
Here's the step by step explanation:
-
When a compound reacts with AgNO3, it forms AgCl. The number of moles of AgCl formed depends on the number of moles of Cl in the compound.
-
In the compound PtCl2 · 4NH3, there are 2 moles of Cl. Therefore, when it reacts with AgNO3, it forms 2 moles of AgCl.
-
However, we are looking for the compound that forms only 50% moles of AgCl. This means we are looking for the compound that forms 1 mole of AgCl.
-
Since PtCl2 · 4NH3 forms 2 moles of AgCl, it forms 50% more AgCl than we are looking for. Therefore, PtCl2 · 4NH3 is the compound that gives only 50% moles of AgCl when reacts with AgNO3.
