What is the solubility of alkali metals in water?
The solubility of alkali metals in water is high. Alkali metals such as lithium, sodium, and potassium readily dissolve in water to form alkaline solutions.
How alum dissolves in the water?
When alum is dissolved in water, it dissociates into its constituent ions: aluminum ions and sulfate ions. These ions are then surrounded by water molecules due to their charges, causing them to become uniformly distributed throughout the water. This process is known as hydration, and it allows alum to dissolve and form a homogeneous solution.
Are metals soluble in water?
Metals are generally not soluble in water, with the exception of certain alkali metals and alkaline earth metals.
What are metals that are less reactive than alkali metals and alkaline-earth metals?
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Are alkaline earth metals reactive to water?
Yes, alkaline earth metals are reactive to water. When they react with water, they form a metal hydroxide and hydrogen gas. However, their reactivity is lower compared to alkali metals like sodium and potassium.

Are metals alkaline?
Yes When metals react with water they produce a metal hydroxide, this contains an OH- ion (which accepts protons and is therefore alkaline) This makes all metals alkaline.
Do both alkali metals and alkaline earth metals form alkaline sollutions when mixed with water?
Yes, it is true.
Does alkaline reacts in water?
Yes, alkaline earth metals react with water forming their hydroxides.
Are metals soluble in water?
Metals are generally not soluble in water, with the exception of certain alkali metals and alkaline earth metals.
A substance that does not dissolve in a solvent is said to be what in that solvent?
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
Are all salts of the earth alkaline metals soluble in water?
Not all salts of the earth alkaline metals are soluble in water. Alkaline metal salts like lithium and sodium salts are generally soluble in water, while salts of heavier alkaline earth metals like calcium and barium may have limited solubility in water.
Compare the alkaline earth metals to the alkali metals according to their reactivity with water?
Alkali metals, such as lithium, sodium, and potassium, are generally more reactive with water than alkaline earth metals like magnesium and calcium. When alkali metals react with water, they produce hydrogen gas and a strong alkaline solution, often resulting in vigorous or explosive reactions. In contrast, alkaline earth metals react with water less violently; for instance, magnesium reacts slowly with hot water, while calcium reacts more readily but still not as explosively as alkali metals. Overall, the reactivity of alkali metals with water is significantly higher than that of alkaline earth metals.
What are metals that are less reactive than alkali metals and alkaline-earth metals?
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Do metals dissolve in water?
Most metals (like Steel, Aluminium, Copper etc.) do not dissolve in water, however there are some (like Sodium) that will.
Why is group 1 metals called alkali metals?
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
