What is the ion responsible for the alkaline property of sodium hydroxide?
The hydroxide (OH-) ion is responsible for the alkaline property of sodium hydroxide. When sodium hydroxide dissolves in water, it releases hydroxide ions, which react with water to form the hydroxide ion, increasing the concentration of hydroxide ions in solution and making it alkaline.
Is sodium hydroxide an alkali or alkaline?
Sodium hydroxide is both an alkali and alkaline. It is classified as an alkali because it dissolves in water to produce hydroxide ions which can react with acidic substances. It is termed alkaline because it has a high pH level and can neutralize acids.
Does sodium react with water to make an alkali?
Yes, sodium reacts with water to form sodium hydroxide, which is an alkaline solution. The reaction is highly exothermic and produces hydrogen gas.
Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
Can an alkaline chemically attack another substance?
Yes, alkaline substances can chemically attack other substances through a process called alkaline hydrolysis. This involves breaking down chemical bonds in the substance through the addition of hydroxide ions from the alkaline solution. Examples of alkaline substances that can cause this reaction include sodium hydroxide and potassium hydroxide.

What does sodium hydroxide and sodium sulfate react to form?
Sodium hydroxide and sodium sulfate don't actually react.
Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
Which gas is liberated when an alkaline solution of sodium nitrate is warmed with aluminium?
Aluminium react with sodium hydroxide releasing hydrogen.Sodium nitrate is decomposed by heating releasing nitrogen dioxide.
Can an alkaline chemically attack another substance?
Yes, alkaline substances can chemically attack other substances through a process called alkaline hydrolysis. This involves breaking down chemical bonds in the substance through the addition of hydroxide ions from the alkaline solution. Examples of alkaline substances that can cause this reaction include sodium hydroxide and potassium hydroxide.
What do metal hydroxides make when they dissolve in water?
Metal hydroxides make alkaline solutions.(e.g sodium hydroxide) Pascal
Does sodium hydroxide react with gold?
Sodium hydroxide (NaOH) does not react with gold under normal conditions. Gold is a noble metal, which means it is relatively unreactive and does not easily react with substances like sodium hydroxide.
Is sodium bi-sulfate react with sodium hydroxide?
Yes, they do react, to form Sodium sulfate and Water
What happens when aqueous ammonia is added to sodium hydroxide?
When aqueous ammonia is added to sodium hydroxide, they react to form a solution of the sodium amide salt and water. The reaction can be represented as: 2NH3(aq) + 2NaOH(aq) → 2NaNH2(aq) + 2H2O(l). The sodium amide formed is a strong base.
What produces OH ions when added to water?
Substances that produce OH- ions when added to water are known as bases, or alkaline substances. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which dissociate in water to release hydroxide ions. These hydroxide ions then react with water molecules to form hydroxide ions (OH-) and hydronium ions (H3O+), leading to the characteristic alkaline properties of bases.
