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 color does onion skin turn in acid and alkali?
Onion skin turns red in acid and green in alkali due to the presence of anthocyanin pigments that change color based on the pH of the solution.
What alkali will turn litmus paper into blue?
Every alkali solution above 7 pH at 298 K would turn red litmus into blue.
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.
What colour will universal indicator turn when acid is mixed with alkali?
Universal indicator will turn green when an acid is mixed with an alkali. This green color indicates a neutral pH level which is achieved when the acid and alkali have neutralized each other.

How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
Are blue blueberries an acidic solution?
Blueberries turn blue at around pH 2.8 -3.2. But it will turn red if it is more acidic.
What color does an alkali turn in a flame?
it depends on what is in the alkali, sodium, calcium, lithium all turn different colours, I believe lithium turns purple, an alkali is a compound with hydroxide ie sodium hydroxide is NaOH

What color does an acid turn if red cabage indacator is added?
Acids turn red/pink when red cabbage indicator is added. Alkali/bases turn blue/green. Neutrals turn purple.
How can you detect the alkali in the water at the end of the reaction of potassium with water?
One way to detect the alkali in water after the reaction of potassium is by using a pH indicator paper, which will turn a specific color in the presence of alkali. Another method is to perform a simple acid-base titration using an acid solution of known concentration and an indicator to determine the amount of alkali present in the water.
What color will phenolphthalein turn in a base?
A phenol red solution is yellow initially. When the solution is exposed to something basic the color will shift from yellow to red to fuschia. Adding enough acid will turn the solution yellow again.
What colour do you get if you mix litmus solution and alkali?
If you mix litmus solution with an alkali, the litmus solution will turn blue. Litmus is a pH indicator that turns red in acidic solutions and blue in alkaline solutions.
