The point in a titration where the reaction is complete and titration should stop
Back
Card 7
Front
An atom or group of atoms that give organic compounds their characteristic reactions
Back
Card 8
Front
Water in which it is difficult to form a lather with soap. It contains calcium and/or magnesium ions which react with the soap to produce scum
Back
Card 9
Front
A group of related organic compounds that have the same functional group, e.g. the molecules of the homologous series of alcohols all contain the –OH group
Back
Card 10
Front
A water softener which works by replacing calcium and magnesium ions with sodium or hydrogen ions, removing the hardness
Back
Card 11
Front
An arrangement of elements in order of their atomic numbers, forming groups and periods
Back
Card 12
Front
Hard water whose calcium and/or magnesium ions are not removed when the water is boiled, thus remaining hard
Back
Card 13
Front
A glass tube used to measure accurate volumes of liquids
Back
Card 14
Front
The insoluble substance formed when temporary hard water is boiled
Back
Card 15
Front
The precipitate formed when soap reacts with calcium and/or magnesium ions in hard water
