The lower the pH, the higher the hydrogen ion concentration, that is more acid. During this time many chapters will be modified, deleted and new chapters might also be added based on the latest education trend Nomenclature, methods of preparation, physical and chemical properties, uses.

This post is to take this discussion a little farther to clarify some points and bring a little closure. Citric acid is found in citrus fruits and is used as a food and drink flavouring, as is tartaric acid.

Priestley reported some of his own discoveries in the second section, such as the conductivity of charcoal and other substances and the continuum between conductors and non-conductors. All three chemicals react with acids to neutralise them. Schofield conjectures that they considered him a heretic.

Any other investigatory project, which involves about 10 periods of work, can be chosen with the approval of the teacher. Study of common food adulterants in fat, oil, butter, sugar, turmeric powder, chilli powder and pepper.
