What type of solution is formed
when the elements of group one react with water? (A) Acidic, (B) alkaline, or (C)
neutral.
The elements of group one include
hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. Excluding hydrogen, these elements
are known as alkali metals. The question asks about the
reaction of these elements with water. All of the alkali metals react with
water in the same way, but the reaction becomes more vigorous as you descend the
group. An alkali metal, denoted M, will
react with water to form an aqueous metal hydroxide and hydrogen gas. As the metal hydroxide contains
hydroxide ions, it produces an alkaline solution. This is how the elements got the
name alkali metals.
Therefore, the type of solution
that is formed when the elements of group one react with water is (B) alkaline.
