What happens when potassium reacts with water.

Its a vigorous reaction that produces alkali potassium hydroxide and hydrogen

2
New cards

What happens when you react a metal w water.

Produces a metal hydroxide (alkali) and hydrogen.

3
New cards

What are reactions of metals with acids.

We o not react the first 4 with acid as the reaction is too vigorous.

What are reactivities of different metals w water.

This is the reactivity series for metals, we can determine the reactivity of the first 4 with water, but cannot determine the last 4 because they dont react w water. Therefore we test reactivity with acid.

New cards

What determines a metal reactivity

When metals react, they lose electrons and form a positive ion.

The reactivity of a metal depends on its ability to lose electrons and form a positive ion.
