PRE-LABORATORY QUESTIONS 1. Given the following two reactants, predict the products of the two reactions. write a balanced equation for each one. Both reactions are acid-base neutralization reactions. ? + ? aj hydrochloric acid + sodium hydroxide b] sulphuric acid + potassium hydroxide ? +? 2. How many grams of KHP, KHC8H404, are needed to react with 38.56 mL of a 0.2500 M sodium hydroxide solution? 3. How many millilitres of a 0.500 M sodium hydroxide solution are necessary to react with 0.250 grams of KHP? 4. 0.150 grams of KHP was titrated with sodium hydroxide. If 29.98 mL of sodium hydroxide was used to reach the end point, what is the molarity, M, of the sodium hydroxide solution? 169

» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or ofter the decimal point. 237 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,210 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures.
