14.3c, 6th edition

Postby Edward Suarez 1I » Sat Mar 16, 2019 2:36 pm

the question is:
write half reactions, balanced equations, and cell diagram of
Cl2 + H2 --> HCl

how do you find the balance equations (liek i thought it would be Cl2 + 2H+ --> 2HCl but the products for anode and cathode respectively were H+ and Cl, why is it like this?

Also how do u know when you need to add Pt(s) in the cell diagram when 13a didn't need it (Based on the answer key)

The products are H+1 and Cl-1 because we know that HCl dissolves in an aqueous solution. To answer your second question, you add a solid such as Pt when there is no solid present to facilitation the transfer of electrons.
