How are the concentrations of hydronium ions and hydroxide ions in aqueous solutions related?

The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.

∙ 11y agoThe concentrations of hydronium ions and hydroxide ions are governed by the equilibrium equation Kw = [H3O+][OH-]. Kw is equal to 10-14, meaning that the product of the concentrations of the aforementioned ions is equal to 10-14.

Meaning that pH is equal to the negative logarithm of the hydronium ion concentration.

Hydronium ions react with hydroxide ions to form?
Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule. Hydroxide ion, OH-, gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water. Combining H3O+ + OH- makes 2 H2O. In other words, an acid and a base combine to neutralize each other as water.
Calculate the hydronium ion concentration in an aqueous solution that contains 2.50 x 10-4 M in hydroxide ion?
4.0x 10^ -11
Aqueous solutions of Barium Nitrate and Sodium Hydroxide are combined Does a precipitate form?
Yes a white precipitate forms when these two solutions are combined.
What is the hydroxide ion concentration in an aqueous solution in which the hydronium ion concentration is 0.13M?
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
What is the product of Aqueous solutions of phosphoric acid and sodium hydroxide are mixed together?
H3PO4(aq)+3NaOH(aq)-->Na3PO4(aq)+3H2O(l)
What conditions must be met in order for an aqueous solution to be neutral?
The concentrations of hydronium and hydroxide ions are equal
What conditions must be met in order for an aqueous solution to be called neutral?
The concentrations of hydronium and hydroxide ions are equal
Describe the relationship between hydronium and hydroxide ion concentrations in an aqueous solution?
The product of hydronium and hydroxide is a constant Kw equal to 1.00*10-14 at 25°C. Therefore, as one increases, the other decreases.
An aqueous solution that contains extra hydroxide ions is?
Basic solutions are solutions that have more than a 1E-7 concentration of hydroxide ion. Thus, solutions with "extra" hydroxide ions are basic. On the other hand, solutions with extra hydrogen (hydronium) ions are acidic.
What is An aqueous solution that contains more hydroxide ions than hydronium ions?
base
An aqueous solution that contains more hydroxide ions than hydronium ions is a acid?
No, it's a base
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.
What is a substance that produces hydroxide ions in aqueous solutions?
Acid
Does a strong base produce the most hydronium ions in an aqueous solution?
No, you mixed it up. Hydronium H3O+ from strong acid and Hydroxide OH- from strong base (alkaline)
Why do hydronium ions form in aqueous acid solutions?
Hydronium ion (H3O+) form in aqueous solution because the water molecule, H2O can accept a proton which is donated from an acid. Thus, the proton (H+) reacts with H2O to produce H3O+, the hydronium ion.
What reacts with water but is not dangerous?
Water reacts with water and isn't dangerous (the equilibrium dissociation of hydrogen into hydronium and aqueous hydroxide).
