Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 15.0 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment. Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first. Record only your final answer with the correct number of significant digits and the proper units.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
