Question

Why will a reaction occur between calcium oxalate and platinum?

Answer 1

The reaction that occurs between calcium oxalate and platinum is called Complex formation.

Step-by-step explanation:

First of all, one might have this belief that there is no possible way a reaction would occur between platinum metal and calcium oxalate, it is taking into consideration because of the relative positions of the two metals in the electro-chemical series.

But in a solution, calcium oxalate seperate into oxalate and calcium ions. when the platinum is put oradded to this solution, a complex is formed between the oxalate ions and platinum ions. then what occurs next is a reaction.

Answer 2

Complex formation

Step-by-step explanation:

At first sight, one may think that a reaction between calcium oxalate and platinum metal is impossible considering the relative positions of the two metals in the electrochemical series.

However, in solution, calcium oxalate dissociates into calcium and oxalate ions. When platinum is added to this solution, a complex is formed between the platinum ions and the oxalate ions. Hence a reaction occurs for this reason.
