A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.

What is the hazard symbol for universal indicator?
The universal indicator itself does not have a specific hazard symbol, but it typically contains chemicals that may be hazardous. When handling universal indicators, one should look for hazard symbols associated with the specific chemicals used in the indicator solution, such as corrosive or toxic symbols. Always refer to the Safety Data Sheet (SDS) for detailed hazard information related to the specific universal indicator product being used.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
Why does universal indicator not always give an accurate result?
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.

What colour is sodium chloride in a universal indicator?
Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.

What is the name of the scale you use to rank the strength of an acid?
The Universal Indicator.
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
What is the colour with universal indicator smelling salts?
The color of universal indicator in smelling salts can vary depending on the specific chemical composition and pH of the salts. However, typically smelling salts with universal indicator will change color to indicate the presence of ammonia gas, which is often associated with a blue or green color change in the indicator solution.
