A mixture of propan-1-ol and 2-methylpropan-2-ol of unknown content may also contain a small amount of water. To determine the% by mass of its propan-1-ol and 2-methylpropan-2-ol content, the mixture was subjected to the following experimental procedures:

A. 2 grams of the mixture is completely burned and 2.24 L of carbon dioxide is produced under normal conditions.

B. B. Equal amount of the mixture (2 g) is transferred to a 250 mL volumetric flask and diluted with distilled water to the mark to give solution Y.

• To a conical flask containing 100 mL of 2 M H2SO4 solution was added accurately 10 mL of solution Y and 15 mL of 0.02 M KMnO4 solution After stirring and gentle heating, the solution S was colorless.

a) Write the chemical equations of the reactions with KMnO4 carried out.

b) Calculate:

(i) the mol of KMnO4 added to the conical flask. (ii) mol of propan-1-ol in 10 mL of solution Y

iii) the percentage by mass (% w/w)of the propan-1-ol mixture content.

1. Some commercial drain cleaners contain a mixture of sodium hydroxide and aluminum powder. When the mixture is poured down a clogged drain, the following reaction occurs: 2NaOH(aq) + 2Al(s) + 6H2O(l) → 2NaAl(OH)4(aq) + 3H2(g) The heat generated in this reaction helps melt away obstructions such as grease, and the hydrogen gas released stirs up the solids clogging the drain. Calculate the volume of H2 formed at 25.5°C and 1.00 atm if 3.75 g of Al is treated with...
