    Gotta do these salts questions.. We were basically told to read the pages on the text book and do the questions and I don't get it at all.. I don't expect you guys to do it for me as I do want to udnerstand it as well, but well I appreciate any help at all

    1. Lead carbonate and lead iodide are insoluble. Which two soluble salts could you use in the preparation of each substance? Write
    a. a word equation
    b. a symbol equation
    c. an ionic equation

    3. An analytical chemist working for an environmental health organizable has been given a sample of water which is thought to have been contaminated by a sulphate, a carbonate and a chloride.
    a. Describe how she could confirm the presence of these three types of salt by simple chemical tests.
    b. Write ionic equations to help you explain what is happening during the rest process.

    IIRC for the first part, look for lead salts that are soluble in water and use two that are above and below each other on the electro-something-or-other series (apologies - I forgot what it's called!)
