Which colour does a strong alkali turn litmus paper?
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
What colour will universal indicator turn when mixed with a strong alkali?
Purple
How can you tell if it is an alkali?
by adding hydrochloric acid to the substance, and if it turns red its a strong acid, if it turns blue its a strong alkali. if its a colour in between like greeny blue or reddy orange, it means it not as strong. Green is neutral XD
What pH a strong alkali have?
a strong alkali has a strong pH of 11-14. 14 being the strongest.
Will a strong alkali dissolve in water?
All types of strong alkali do not dissolve well in water. Magnesium hydroxide can be given as an example for an insoluble strong alkali.
What colour would a UI be in strong acid?
The answer is...RED!!!!Strong Alkali is DARK BLUE!!!

What is indicat?
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.

What is the reaction when you add acids and alkali's?
you create a neutral solution -------------------------------------------------------------------------------------------- Well it depends actually it doesn't always create a neutral solution. Here's the order: Strong Alkali + Strong Acid = Neutralisation (water + salt) Strong Alkali + Weak Acid = Weak Alkali Weak Alkali + Weak Acid = Neutralisation ( water + salt) Weak Alkali + Strong Acid = Weak Acid Strong Alkali + Strong Acid = Neutralisation (water + salt) Hope it helps! :)
Is KOH a weak or a strong alkali?
Strong
