Can someone help with this question?
« on: September 22, 2022, 12:01:53 PM »
A container contains a solution of HCl(aq)0.5M, someone added 12gr of Fe(s). The chemical reaction formed FeCl3(aq) and H2(g).
1. What is the volume of acid that reacted?
2. What is the concentration of the cations and the concentration of the anions in the solution (use the volume from the first question)?

In general it is a good idea to write a balanced equation.

Hi, thank you for your response

This is what I have done
6HCl(aq)+2Fe(s) :rarrow: 3H2(g)+2FeCl3(aq)
0.5M=0.21mol/X
x= 0.42L
FeCl3(aq) :rarrow:H2OFe3++3Cl-

I just don't understand how to solve the second question

How many moles of Fe3+? In what volume? What is the concentration of Fe3+ then?

Same about Cl-.
