Do basic compounds produce OH- ions when dissolved in water?

Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.


Gas whose aqueous solution is basic?

Ammonia gas when dissolved in water produce Ammonium hydroxide so its solution is basic.


Why doesn't chlorine produce a basic solution when dissolved in water?

Chlorine gas dissolves in water to form hydrochloric acid (HCl), not a basic solution. When dissolved in water, chlorine gas reacts with water to produce hydrochloric acid and hypochlorous acid, which is a weak acid. This reaction contributes to the acidic nature of the solution, rather than making it basic.


Which substance will produce a solution with a basic pH when dissolved in water?

Most metal hydroxides and oxides e.g. K2O and KOH


Is Ca CO acidic basic or neutral?

Calcium carbonate (CaCO3) is a basic substance because it is an alkaline compound. When dissolved in water, it will produce a slightly basic solution.


When a non metal oxide is dissolved in water is the solution acidic or basic?

When a non-metal oxide, such as sulfur dioxide, is dissolved in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acids.


Why aqueous solution of oxide of calcium is basic?

Aqueous solutions of calcium oxide (CaO) are basic because they produce hydroxide ions when dissolved in water. Calcium oxide reacts with water to form calcium hydroxide, which dissociates to release hydroxide ions, increasing the pH of the solution and making it basic.


Is barium nitrite basic acidic?

Barium nitrite is considered basic because it can form hydroxide ions in solution. When dissolved in water, it will produce barium hydroxide, which can partially dissociate to release OH- ions, making the solution basic.


Is soap a base for litmus paper?

Yes, dissolved soap is a basic solution.


What does a base produce when dissolved in water?

When bases dissolve in water, they usually form alkaline solution. An alkaline solution has a pH that is more than seven.


What is a solution and what are the 2 basic parts of a solution?

solute is the substance being dissolved, solvent is the substance doing the dissolving. A solution is a mixture, not a compound. There is no exact formula for a solution, there can be a small amount dissolved (called a dilute solution) or a large amount dissolved (called a concentrated solution). Sugar in water is a solution, sugar is the solute, water is the solvent.


Is calcium cyanide acidic or basic?

Calcium cyanide is basic. It forms hydroxide ions when dissolved in water, making the solution basic.
