2.  If a VOLUME is mentioned, and the problem involves molarity DO NOT assume that 22.4L should be used. STP is only used when it says STP in the question and the substance is a GAS!

3.  Solutions of ammonia and phosphoric acid are used to produce ammonium hydrogen phosphate fertilizer. What volume of 14.8mol/L ammonia is needed to react completely with 1.00L of 12.9mol/L phospheric acid to produce fertilizer?

4.  A technician determines the amount concentration of sulfuric acid solution. In the experiment, 10.00mL of sulfuric acid reacts completely with 15.9mL of 0.150M potassium hydroxide. Calculate the concentrations of sulfuric acid.

5.  A titration is a process in which a measured amount of a solution is reacted with a known volume of another solution (one with an unknown concentration) until a desired equivalence point is reached

6.  The equivalence point is the point in a titration where the ratio of the moles of each species involved exactly equals the ratio of the coefficients of the species in the balanced reaction equation.

7.  Assume a beaker contains 0.0250L of H2SO4. A graduated tube (burette) is used to slowly add NaOH solution. At the instant that 15.6mL of the 3.2M NaOH has been added, that is, the equivalence point has been reached, the titration process is stopped.

8.  Consider the reaction between phosphoric acid and potassium hydroxide.  Complete the chart provided
