Inorganic 'mini problems' help
« on: April 29, 2018, 12:20:56 PM »
Hi,

I have my inorganic final exam in a couple of weeks, and every year they seem to ask one of these so called 'inorganic mini problems' with quite a few unknowns in them. I usually have no idea where to start and how to approach these problems and I was wondering if I could have some general guidance as for how I can systematically go through and solve these problems. Any help is appreciated.

There is an "Additional options" button below the edit field in which you typically compose your message.

Start by listing all knowns and all related equations. Is there anything you can calculate from the information about the amount of the lead bromide?

I'd suggest you start by determining the mass of bromine in the lead (II) bromide.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Orange coloured salt indicates mostly transition metals. Consider which oxidation number (indicates variable n) is the common one for that.
