Is magnesium or sodium more reactive?
Magnesium is less active than sodium; calcium is less active than potassium; and so on. These metals become more active as we go down the column. Magnesium is more active than beryllium; calcium is more active than magnesium; and so on.
What are 3 facts about alkali metals?
Interesting Facts about Alkali Metals
- Because they are so reactive with air and water, they are generally stored in oil.
- Cesium and rubidium are used to make atomic clocks.
- Sodium and potassium both play an important role in biological life on Earth.
- Sometimes cesium is also spelled “caesium.”
Which alkali metal is most reactive with water?
Sodium
How can you tell that a metal is reacting with water?
Reactions of metals with water
- When a metal reacts with water, a metal hydroxide and hydrogen are formed.
- For example:
- sodium + water âžž sodium hydroxide + hydrogen.
- calcium + water âžž calcium hydroxide + hydrogen.
- The apparatus below is used to react calcium with water and collect the gas.
What does a metal oxide and acid make?
A salt and water are produced when acids react with metal oxides .
How are metal oxides formed?
Oxides typically react with acids or bases, sometimes both. Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals (metalloids).
What happens when a metal oxide dissolves in water?
Metal Oxide reactions The oxides of metals are basic. If a metal oxide dissolves in water, it will form a metal hydroxide. Like any base, these bases can be neutralized by an acid to form a salt and water.
Does Aluminium oxide dissolve in water?
Aluminium oxide is amphoteric. It has reactions as both a base and an acid. Reaction with water: Aluminum oxide is insoluble in water and does not react like sodium oxide and magnesium oxide. The oxide ions are held too strongly in the solid lattice to react with the water.
What is the chemical symbol of oxide?
Oxide(2-) is a monoatomic oxygen. Binary compounds of oxygen containing the anion O(2-)….4.3Related Element.

What happens to an acid or a base in water solution?
Acid and bases in water Acids in water solution dissociate H+ ions. Base, when dissolved in water, produces OH– ion. When an acidic solution is diluted with water, the concentration of H+ ions decreases and the pH of the solution increases towards 7.
What is produced when a base is dissolved in water?
hydroxide ions
Is water an acid or a base?
Pure water is neither acidic or basic; it is neutral.
