precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the addition of hydrochloric acid. The precipitate will reappear ...

A neutralisation reaction is one in which an acid reacts with a base to form water. A salt is also formed in this reaction. Bases are metal oxides, metal hydroxides and metal carbonates.

The metal in question is sodium. Normally, it isn’t transparent, but molten sodium hydroxide does turn transparent after it — well, sort of explodes. Of course, sodium hydroxide isn’t really ...

They can attack metals and destroy skin if spilled ... acid.Here are the equations for the reaction: sodium hydroxide + hydrochloric acid → sodium chloride + water Just enough hydrochloric ...

The solutions will become cloudy and change color due to the precipitation of metal hydroxides. Add 15M NH4OH with stirring to the same beaker or test tube. The precipitates will dissolve and darkly ...
