1. The acidity of a water sample can be measured by a neutralization reaction with a solution of sodium hydroxide, NaOH(aq). what is the concentration of hydrogen ions in a water sample if 100 mL of the sample is neutralized by the addition of 8.0 mL of 2.5x10-3 mol/L sodium hydroxide ?
2. Write the net ionic equation for this reaction: Mgcl2(aq) + NaOH(aq)-Mg(OH)2 (s) + NaCl(aq)
3. What volume of 1.25 mol/L potassium iodide solution can you make with 125 mL of 3.00 mol/L potassium iodide solution ?
