What else can I help you with?
Is magnesium oxide aqueous?
No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?
You would observe precipitation of magnesium hydroxide.
Is an aqueous solution of calcium hydroxide acidic or basic?
This solution is basic.
Is an aqueous solution of ammonia alkaline in nature?
Yes, this solution (NH4OH, ammonium hydroxide) is alkaline.
Is barium hydroxide aqueous or solid?
Barium hydroxide is typically encountered as a solid at room temperature. However, it can dissolve in water to form a barium hydroxide solution, which is referred to as aqueous barium hydroxide. In its solid form, barium hydroxide appears as a white crystalline substance. When dissolved in water, it can produce a strongly alkaline solution.
Which hydroxide compound yields the lowest concentration of hydroxide ions in aqueous solution?
Aluminum hydroxide (Al(OH)3) yields the lowest concentration of hydroxide ions in aqueous solution due to its low solubility. This makes it a weak base compared to other hydroxide compounds.
What is the chemical formula for aqueous magnesium hydroxide?
The chemical formula of magnesium hydroxide is Mg(OH)2; this compound is extremely low soluble in water.
What statement about Arrhenius acids is FALSETheir aqueous solutions are electrolytesTheir water solutions are called aqueous acids They increase the concentration of hydroxide ions in aqueous solutionThey are molecular compounds with hydrogen ions?
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
Is magnesium oxide aqueous?
No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
Which base is strong but never concentrated?
A strong base that is not concentrated is an aqueous solution of a weak base. Weak bases have a lower concentration of hydroxide ions compared to strong bases but can still exhibit some degree of basicity. Examples include ammonia (NH3) and bicarbonate (HCO3-).
What is an aqueous solution of a base called?
An aqueous solution of a base is called an alkali solution. Alkalis are compounds that release hydroxide (OH-) ions in water, leading to an increase in the concentration of hydroxide ions in the solution. This results in a solution with a pH greater than 7.
What is an aqueous solution that contains more hydroxide ions than?
An aqueous solution that contains more hydroxide ions than hydrogen ions is considered a basic solution with a pH greater than 7. This solution is known as an alkaline solution and has a higher concentration of hydroxide ions, making it a stronger base.
What happens to OH in an aqueous solution when H3O increases?
As the concentration of H₃O⁺ increases in an aqueous solution, the pH decreases, shifting the equilibrium of the autoionization of water to the left. This results in a decrease in the concentration of hydroxide ions (OH⁻) in the solution.
What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?
You would observe precipitation of magnesium hydroxide.
Which term is applied to an aqueous solution whose hydrogen ion concentration H plus is less than its hydroxide ion concentratio OH?
The term applied to an aqueous solution with a hydrogen ion concentration (H+) lower than the hydroxide ion concentration (OH-) is basic or alkaline. This indicates that there are more OH- ions present, making the solution basic on the pH scale.
What is the word equation for solid magnesium hydroxide reacts with a hydrobromic acid solution to produce aqueous magnesium bromide and water?
The part of this question after the word "for" is the answer to the question!
Why magnesium hydroxide a weak alkali?
Magnesium hydroxide is considered a weak alkali because it has limited solubility in water, which restricts the number of hydroxide ions (OH⁻) it can release into solution. When dissolved, it dissociates only partially, resulting in a lower concentration of hydroxide ions compared to strong alkalis like sodium hydroxide. This partial dissociation means that its ability to neutralize acids and raise pH levels is less potent than that of stronger bases. Consequently, magnesium hydroxide exhibits weaker alkaline properties in aqueous solutions.
