How much would a dosage of 12ml 10% Potassium Iodide (KI) w/v solution increase Iodide levels in a total voluve of 800 liters?
The concentration of iodide, or
First, start by figuring out exactly how much iodide you'll be adding to the tank. Use the given
In your case, a 10% w/v solution would have 10 g of potassium iodide for every 100 mL of solution. As a result, the 12-mL sample will contain
Use potassium iodide's molar mass to determine how many moles you get from that mass
Now, because potassium iodide fully dissociates in aqueous solution into
It is safe to assume that the added
Therefore, the added concentration of iodide in the tank will be
Rounded to one sig fig, the number of sig figs in 800 L, the answer will be
SIDE NOTE. Keep in mind that the concentration is milimolar, not molar.
