Mr. Kent's Chemistry Regents Help and AP Chemistry Exam Review Pages

Titration Calculations Before you go any further, check that you can do the following… Calculate: Relative molecular masses from a given chemical formula Calculate: Number of Moles from the mass/RMM equation Manipulate: The number of moles equation to get the form you require. When you are confronted by a Titration calculation the first rule is: The Second rule is read through the question very carefully. The Third rule is read through the question carefully again! We are now going to look at a question and hopefully guide the unbelievers (henceforth known as infidels) through a titration calculation. The question: 10.0 cm3 of a solution of potassium hydroxide was titrated with a 0.10 M solution of hydrochloric acid. 13.5 cm3 of the acid was required for neutralization. Step 1 Write down everything you know. Hydrochloric Acid Potassium hydroxide Volume used = 13.5 cm3 Volume used = 10.0 cm3 Concentration = 0.10 M Concentration = TBD Step 2 Write the equation or as much as you know about it. Step 3 Step 4 Questions 1. 2.

Royal Society of Chemistry | Advancing the Chemical Sciences Practical Chemistry.org This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5.
