They are called acid/base indicators
A buffer is supposed to keep the pH of a solution from fluctuating too much. It helps keep the pH more-or-less consistent. Whether it keeps the solution neutral, it doesn't have to be neutral. You can make a solution be whatever pH you want, but different solutions and pHs require different approaches.
The acidity or alkalinity of a substance can be determined using a pH indicator. pH indicators change color depending on the pH of a solution, allowing for the determination of whether the substance is acidic, neutral, or basic.
pH level Check the pH level of the solution with a piece of litmus paper.
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
A dye that changes color depending on whether it's exposed to an acid or alkaline solution is called a pH indicator. pH indicators are commonly used in chemistry labs to determine the acidity or alkalinity of a solution based on the color change they undergo.

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.

Depending on whether "this" is supposed to be neutral (or unknown), male, or female: "esto es", "este es", "esta es".
The pH of the solution can tell if it is acidic or alkaline. For acids, pH will be 1 to 7 and for alkaline it will be around 8 to 14. pH of 7 is for neutral solution.
pH level Check the pH level of the solution with a piece of litmus paper.
It is a point that may or may not be a solution to the system - depending on whether or not the inequalities are strict.
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
pH paper is of extreme importance to a scientist who is working with an unfimiliar chemical or solution. pH paper tells whether the object is acidic, alkali (basic), or neutral. If red pH paper turns blue when dipped into a solution, it means the solution is an alkali. If blue pH paper turns red when dipped in a solution, it means it's acidic. and if neither the red nor blue pH paper turns any color, its neutral. A scientist who wants to combine a solution with something must know whether it's acidic, alkali, or neutral so as to not have an uncontrolled reaction. When acids mix with bases, it usually means an explosion or some kind of reaction.
An acid base indicator is used for determining the pH of a solution, and determining if it is an acid, a base, or neutral solution. Red-ox indicators are used to check whether a desired red-ox reaction has proceeded to its completion.
