Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution

What is an acid reaction?
If you have an acid of unknown strength, you add Universal Indicator & add drops of a base. Count the drops of the base until the solution turns green (neutral) This should tell you how strong the acid is. This can also be done the other way (with a base of unknown strength & adding an acid) Does that make sense?
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
What is the purpose of adding NaOH to the mixture before taking the polarimeter reading?
It is to neutralize the solution and to stop the hydrolysis.
What is the purpose of adding sodium hexametaphosphate solution to the soil suspension during particle-size analysis?
it is very nonsense
What is titration used in the medicine industry?
Medicine is uses to reduce a patient until they are heal. In particularly in chemistry is it the process of finding a concentration of a certain reactants in solutions. This functionality, titration is also known as volumetric analysis, due to a heavy reliance on the measurement of volume and concentration. Titration involves taking an agent of unknown concentration and adding it to a solution. The agent is often known as the titrant and the purpose of adding it o a solution is to create a measurable reaction with the unknown agent. The scientists have to find the exact concentration of unknown agent, also known as the analyte. The concentration of the analyte will not found until the reaction has finished. Often the solution that will change colour to give and assessable endpoint to the reaction.
What is the material used to remove an indicator from a neutralized solution how does this work?
it is universal indicator with mixture of alkali
What is the purpose of adding water to the base?
To prepare a dilute solution.

If you are trying to create a neutral salt from a base by adding an acid but the pH indicator indicates that the solution is now acidic what should be your next step?
add a base to the solution
Why does adding carbon dioxide to BTB solution cause a color change?
BTB is an acid indicator. by adding carbon dioxide to the solution, it will turn into carbonic acid (a weak acid) turns green in low concentration and yellow in high concentration.
Why does adding 6 M HCl to the yellow solution of methyl red tend to cause the color change to red?
Methyl is an indicator, when HCl, which is an acid, is added, the solution will turn red.

What is the purpose of adding rose Bengal and streptomycin solution in the rose Bengal agar medium?
The purpose of both is to inhibit bacterial growth. The media is used for growing fungi.
What is the type of test used to show color changes of certain water solutions?
adding what is called an indicator such as phenolphthalein which is colorless in an acidic solution, but turns pink in an acid solution often used in a test called titration
