Is potassium oxide an alkaline?
No Potassium oxide is extremely basic (alkaline).
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.
Is calcium oxide a basic oxide?
Yes, Calcium oxide is an alkaline as when Calcium oxide reacts with water (H2O) it dissolves as it is a soluble metal oxide. The solution produced when this occurs is an alkaline solution. This proves that Calcium oxide is an alkaline
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.
Which element produces a red flame when it reacts with water?
Lithium is the element that produces a red flame when it reacts with water.
What reacts with water to give a white alkaline solid?
Calcium oxide (CaO) reacts with water to give a white alkaline solid called calcium hydroxide (Ca(OH)2).
When calcium reacts with water is the solution formed acidic alkaline or netural?
Ca + 2H2O --->Ca(OH)2 + H2 Solution is alkaline
Which group above 9-12 reacts with water to yield alkaline solution?
These are the alkali metals.
What is the formula and name of the compound that makes the solution alkaline when rubidium reacts with water?
Rubidium hydroxide, RbOH.
What colour does phenolphthalein change to when it reacts with and alkaline solution?
Phenolphthalein changes from colorless to pink when it reacts with an alkaline solution.
Is sodium bicorbonate acidic or basic in water?
Sodium bicarbonate is slightly basic in water as it reacts with water to produce hydroxide ions (OH-) which make the solution slightly alkaline.
Is magnesium oxide an alkaline solution?
It is a white crumbly slightly alkline(10.3) substance
What happens when magnesium reacts with water?
Producing a solution, Mg(OH)2 that is only slightly alkaline, ph~8

Does sulfur dissolve in water to produce an alkaline solution?
No. However it will dissove in water to produce an acidic solution :)
What has an oxide which reacts with water to gie an alkaline solution?
Metal oxides such as calcium oxide (CaO) and magnesium oxide (MgO) react with water to form alkaline solutions. This process is known as slaking, where the metal oxide reacts with water to form metal hydroxide, releasing heat in the process.
