A common solution used to stabilize pH is a buffer solution, which resists changes in pH by absorbing excess hydrogen or hydroxide ions. Buffers are composed of a weak acid and its conjugate base (or a weak base and its conjugate acid), helping to maintain pH within a desired range.
Chemicals such as buffers, like sodium bicarbonate or sodium hydroxide, can be used to help stabilize pH levels when acids are added to a solution. Buffers work by resisting changes in pH by neutralizing the added acid.
This depends on its concentration. In a 1M ammonia solution (my guess is 17g/L), about 0.42% of the ammonia is converted to ammonium (my guess is 0.07 g/L), equivalent to a pH of 11.63.
Universal pH paper is a type of indicator paper that changes color based on the acidity or alkalinity of a solution. It covers a wide pH range and can be used to quickly determine the approximate pH of a liquid.
Compounds like buffers, such as bicarbonate ions or phosphates, can stabilize the pH of a solution by either accepting or donating hydrogen ions to maintain a relatively constant pH level. By absorbing excess hydrogen ions or releasing them as needed, these compounds help prevent drastic changes in pH.
A buffer is used in a system to help regulate and stabilize the pH level, or acidity, of a solution. It works by resisting changes in pH when an acid or base is added to the solution, helping to maintain a relatively constant pH level. This is important in various biological and chemical processes where maintaining a specific pH range is crucial for proper functioning.
A pH indicator is used only to measure the pH of the solution.
Buffer solutions work to stabilize the pH of a solution by resisting changes in pH when acids or bases are added. This is achieved by the presence of a weak acid and its conjugate base (or a weak base and its conjugate acid) in the solution, which can react with any added acid or base to prevent drastic changes in pH.

A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.

Adding an acidic solution.
Are you sure the liquid of pH 3 is actually not an aqueous solution? The pH7 is probably water, which doesn't matter in the equilibrium equation. So I would say pH3 assuming the liquid was supposed to be an aqueous solution of a decently strong acid.
Buffer solutions are compounds that in solution maintain pH within given limits by resisting changes in pH when an acid or base is added. Buffers typically consist of a weak acid and its conjugate base, or a weak base and its conjugate acid, which help stabilize the pH of the solution.
Orthophosphoric acid is commonly used as a buffer in redox titrations to maintain the pH of the solution. It also helps to prevent changes in pH that could interfere with the redox reaction being monitored. Additionally, it can complex with metal ions, helping to stabilize them in solution.
