bases Flashcards
whats a base
a metal oxide or metal hydroxide that neutralises in an acid to produce a salt
whats the equation for acid and bases
acid + base = salt + water
the base can be metal oxide or metal hydroxide
what would copper oxide and sulfuric acid make
whats the observations
copper sulfate + water
black solid copper oxide disasppers a blue solution produced
what are most group 1 and group 2 salt colour what colour will they go dissolved in water
white to colourless in water
whats a salt
A salt is a compound formed when some or all of the hydrogen ions in an acid are replaced by metal ions or ammonium ions
what colour does copper sulfate change to when heated
Copper(II) sulfate changes from blue crystals to a white powder when it is heated
if a solid/compound metal reacts with the excess of a acid what will happen with the solid
the solid will disappear
the solid will disappear
what colour solutions are all acids
colourless
what is concentration measured in
mol per dm3
what are the common bases
oxides and metal hydroxides
whats a alkali
a soluble base
