A hydroxide ion.
No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.
A substance that increases the concentration of hydroxide ions in solution (OH-), is referred to as an Arrhenius base.
it is a base
It increases the concentration of OH - in a solution.
As a general rule of thumb, for acid solutions [H+] > [OH-], for basic solutions [H+] < [OH-], and for neutral solutions or for pure water [H+] = [OH-] This is the answer but can someone explain it to me?
A solution of the base in water. Like with acids you would get partial dissociation however. eg for NaOH, it would mostly split up into Na+ and OH-.
Any solution that has a pH level higher then seven is going to contain the higher concentrations of hydroxide. The gastric acid located in the stomach has very high concentrations of hydroxide.
An Arrhenius base produces OH- ions.
When a strong base is dissolved in water , OH ion concentration will be high.
For a weak acid (or base), as the concentration increases, the % ionization/dissociation decreases. This leads to fewer ions in solution, and hence the molar conductivity decreases.
Acids have more hydronium than hydroxide. Bases are the reverse of that.
