How to view saved passwords on Chrome iOS?
You can't review your stored Passwords in the Chrome App at all.

On the App and in the Support Documents Apple mentions  to use the url passwords.google.com see 

On that Page when you open it on your Moblie it says that you can access your Passwords From all your Divices but not fron this Site see 

So i think there is currently no way you can have a Look at your saved Passwords at the Moment.

If you realy need it you should Fill a Bug request and send it to Google so they maybe will fix it in the App.
