There is multiple, the most common would probably be Litmus Paper and Universal Indicator. The properties they have (the relavent ones) is that they turn a certain color when mixed with an acid or base.

The plural of practicum is practicums or the little-used practica.
There are many different indicators in chemistry which can be blue. Some indicators indicate the presence of a species such as a metal ion, whereas others are pH sensitive. The exact meaning depends on the specific indicator used. For example, blue litmus paper indicates a basic solution.
Absorbing indicators are substances that can absorb light at a specific wavelength and then emit light at a longer wavelength. These indicators are commonly used in chemistry for analyzing the presence or concentration of certain compounds in a solution based on the color change they produce.
pH indicators in chemistry to determine the acidity or basicity of a solution. These dyes change color depending on the pH of the solution, making them useful for identifying pH levels in experiments or quality control.

Metallochromic indicators are chemical compounds that change color when they bind to metal ions. They are commonly used in analytical chemistry to detect the presence of metal ions in a solution. The color change is due to the formation of a complex between the indicator and the metal ion.
Density, crystallography, mineralogy, method of formation, chemistry, texture, hardness, and others.
It is actually a chemical word used during titration.in chemistry practicals endpoint are given to enable student work along the given point or titre value.if the endpoint of a student during practical surpass that of the teacher he needs to recheck his calculations again.
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
Halogens have various practical uses, such as disinfectants (chlorine), in producing plastics (fluorine), in photography (bromine), and in water purification (iodine). They are also used in manufacturing medicines and chemicals.
