What is the specific name of universal indicator?
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 will salt solution turn into with universal indicator?
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
What does universal indicator contain?
Universal indicator is a mixture of several different dyes that change color in response to different pH levels. This allows it to provide a visual indication of the acidity or alkalinity of a solution across a wide range of pH values.
How does universal indicator show that acids are neutralised by carbonates?
Universal indicator changes color from red (acidic) to green or blue (neutral) when an acid is neutralized by a carbonate. This change occurs because the carbonate reacts with the acid to form a salt, water, and carbon dioxide, making the solution less acidic and approaching neutrality.
What is the colour of phenolphthalein in salt water?
It will turn purple
What colour does universal indicator go if salt solution is added?
red
What colour uvirsal indicator go if added to soudium chloride?
Sodium Chloride a.k.a. table salt or sea salt is neutral and so Universal Indicator will go Green with a Ph 7

The name of the plant which universal indicator is made of?
From wikipedia: A universal indicator is typically composed of water, methanol, propan-1-ol, phenolphthalein sodium salt, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt
What will salt solution turn into with universal indicator?
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
Universal indicator is a mixture of what?
Universal indicators can be mixed with different substances. Universal indicators usually contain water, salt, propan-1-ol, sodium hydroxide, monosodium, phenolphthalein sodium salt, methyl red, bromothymol blue, and thymol blue monosodium salt
What colour does universal indicator turn in ammonia solution?
Universal indicator turns blue or purple in ammonia solution. Ammonia is a weak base, so it causes the indicator to change to a blue or purple color on the pH scale. This color change indicates the basic nature of the solution due to the presence of ammonia molecules.
What colour will the indicator turn when the right amounts of acid and alkali have been combined to make a solution of salt and water?
The indicator will turn green when the right amounts of acid and alkali have been combined to make a solution of salt and water. This indicates that the solution has reached a neutral pH level.
Why salt as a universal solvent?
Salt is not a universal solvent. Water is often referred to as the universal solvent due to its ability to dissolve a wide variety of substances. Salt, on the other hand, is a solute that can dissolve in water or other solvents to form a solution.
How do you make a universal indicator?
Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
What does universal indicator contain?
Universal indicator is a mixture of several different dyes that change color in response to different pH levels. This allows it to provide a visual indication of the acidity or alkalinity of a solution across a wide range of pH values.
Is it possible to mix fresh water and salt water?
yes.water is a universal solvent
