GCSE CHEMISTRY What is Acid Rain? GCSE SCIENCE

What causes Acid Rain? Coal, oil and natural gas contain sulfur. When they are burnt in a power station the sulfur oxidises (reacts with oxygen) to form sulfur dioxide gas. sulfur + oxygen sulfur dioxide. S (s) + O 2(g) SO 2(g) Sulfur dioxide gas is acidic, poisonous, and smells like burnt matches....

GCSE CHEMISTRY What is Neutralization? What is a Salt ...

A pH of 7 is neutral. An acid has a pH of less than 7. An alkali has a pH of more than 7. An acid is neutralised when it reacts with an alkali, a base a carbonate or a metal. When neutralisation is complete there is no more acid left, the pH is 7 and the solution will contain a neutral salt....

: Reactions: Acids and Bases

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H 2 O) can be both an acid and a base, depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases....

Esters (GCSE)Structure Esters have the functional group –COO– Production Ethyl ethanoate (CH3COOCH2CH3) is the ester produced from ethanol and ethanoic acid in the presence of concentrated sulfuric acid catalyst. Properties They are volatile compounds with distinctive smells and are used as flavourings and perfumes....

CONTACT Process: Manufacture of Sulphuric Acid: IGCSE ...

Stage 3: Making the sulfuric acid You can react sulfur trioxide with water to make sulfuric acid. SO 3 (g) + H 2 O(l) > H 2 SO 4 (aq) In practice, this produces an uncontrollable fog of concentrated sulfuric acid. Instead, the sulfur trioxide is absorbed in concentrated sulfuric acid to give fuming sulfuric acid (also called oleum)....
