Why does the pH of water change after a reaction with an alkali metal?
Yes, the pH increases because the alkali metal atoms replace some hydrogen ions in the water with alkali metal ions.
What is the charge on an alkali metal ion?
the charge on all alkali metal ions is 1 +
What is the charge of all alkali metal ions?
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
How do you use the periodic table to recall the ionic charge of alkali metal an alkaline earth metal or aluminum?
The ionic charge depends on the number of valence electrons. Alkali metals, alkaline earth metals and aluminium have 1, 2 and 3 valence electrons respectively and will hence form ions with +1, +2 and +3 charges respectively.

Why sodium carbonate being a salt acts as an alkali metal?
It is not an alkali metal, but it is alkaline. The carbonate ion is a weak base; it reacts with water in small amounts to form bicarbonate ions and hydroxide ions.
What is the most common oxidation state on the ions for alkali metal?
The oxidation state is 1.
What is ion for Mg?
Magnesium is an alkali earth metal, so it makes only +2 ions: Mg2+
Does cesium form Cs plus or Cs2 plus ions?
As it is an alkali metal, it forms the Cs+ ion
Do all bases contain hydroxide ions?
A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
