What exists in aqueous solution an acid or base?
An acid exists in aqueous solution when the concentration of H+ ions is higher than that of OH- ions, resulting in a pH lower than 7. A base exists in aqueous solution when the concentration of OH- ions is higher than that of H+ ions, resulting in a pH higher than 7.
Is aqueous ammonia a base or an acid?
Aqueous ammonia is a base. It readily accepts a proton from water to form ammonium ions and hydroxide ions, increasing the pH of the solution.
Suppose you wanted to produce an aqueous solution of pH 8.75 by dissolving potassium nitrate in water what is the molarity?
Not likely. Potassium nitrate, KNO3 is the salt of a strong acid (HNO3) and a strong base (KOH). Thus, the pH of a solution of KNO3 will be very close to pH=7, depending really on the pH of the water used to make the solution. There is no way to get it to pH = 8.75. You'd need to used something like potassium acetate, the salt of a strong base and a weak acid.
What products are formed when the aqueous ammonia is added to polyacrylic acid and and how to calculate the pH of the produced solution?
When aqueous ammonia is added to polyacrylic acid, the products are the ammonium salt of polyacrylic acid and water. To calculate the pH of the solution, you would need to consider the equilibrium between the acid (polyacrylic acid) and its conjugate base (ammonium polyacrylate). You can determine the pH based on the concentration of the acid, the equilibrium constant, and the dissociation of the acid.
Is ammnia an acid or a base?
"Ammonia", NH3, is a fairly strong base having at 1M concentration in aqueous solution a pH of 11.6

How does an acid and base differ in meaning?
An acid solution has a pH under 7.A base solution has a pH over 7.

When you lower the pH of a solution containing aqueous sodium benzoate a precipitate eventually forms What will happen if you then raise the pH after the reaction by adding aqueous NaOH?
When you raise the pH by adding aqueous NaOH after a precipitate forms in a solution of aqueous sodium benzoate due to a pH decrease, the precipitate likely dissolves. This is because sodium benzoate is the conjugate base of benzoic acid, so at higher pH levels, it remains in solution. The sodium benzoate will revert back to being fully soluble in its aqueous form.
The pH of a 1.0 M aqueous solution of NaNO3 will be?
The pH of a 1.0 M aqueous solution of NaNO3 will be around 7, which is considered neutral. Sodium nitrate is a strong electrolyte that dissociates completely into Na+ and NO3- ions, neither of which will affect the pH of the solution significantly.
What does it mean to neutralize a solution and how can this be done?
Neutralizing a solution involves adjusting its pH to make it neither acidic nor basic. This is usually done by adding an acid to a basic solution or a base to an acidic solution until the desired pH is reached. Different chemicals can be used depending on the initial pH of the solution and the desired final pH.
What is the acidic solution of pH?
Any aqueous solution will have a pH lower than 7.00 in order to be considered acidic.
What happens to the pH of An aqueous solution if a few drops of acid are added to it?
If the solution is not basic then the pH will fall below 7
Is ammonia low pH?
Ammonia is a basic gas. It shows high ph if it is dissolved in water.
