flame test for calcium (Ca2+)

Back (Answer)

orange - red

#15
Front (Question)

why are all the metals in flame tests positive ions

Back (Answer)

oxygen is a negative ion - it reacts with oxygen to produce the coloured flame

#20
Front (Question)

chemical test to show a liquid contains water

Back (Answer)

add water to anhydrous white copper sulphate. will turn blue

#21
Front (Question)

physical test for pure water

Back (Answer)

freeze or boil - if it is the pure then it will be the same as water (100 degrees or o degrees)

#22
Front (Question)

physical test for normal water

Back (Answer)

boils at or around 100 degrees

#23
Front (Question)

chemical test for pure water

Back (Answer)

set up a simple circuit with a light bulb. if bulb does not light up then it is pure water. if bulb does light up it is likely normal water as normal water can conduct some electricity

#24
Front (Question)

What is test for the presence of carbonate ions

Back (Answer)

add hydrochloric acid. will produce carbon dioxide bubbles. test for carbon dioxide with lime water.
