To test a water sample for lead, 25 grams of sodium chloride is dissolved into 100.0 mL of the water. If no precipitation occurs, the concentration of lead(II) ions in the water is below what concentration?
Suppose 0.425g of sodium chloride is dissolved in 50.mL of a 0.50 M aqueous solution of silver nitrate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the sodium chloride is dissolved in it. Be sure your answer has the correct number of significant digits.
