Question

By now, you all know that silver iodide is very insoluble in water. Chemists know that by adding a very slight excess of silver nitrate to an iodide containing solution it is possible effectively to remove all the iodide ion from the sample. First, write a balanced net ionic equation for this reaction. Then, assume that 2.375 grams of silver iodide were formed on the reaction of the sample and AgNO3. If the % iodide in the sample was 22.50%, how many grams of AgNO3 were required and what was the mass of the sample?
