Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.
Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.
Look at Universal Indicator Solution.

How to lower alkali in water?
Add acid
What happens whey you add acid to alkali the pH solution gets?
it changes its colour into red.
How do you neutralize a acid or alkali?
To neutralise an acid add sodium carbonate. 2H^+ + Na2CO3 = 2Na^(+) + H2O + CO2 It forms the salt , water and carbon dioxide. To neutralise an alkali add 'milk'.
What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
What happens when an acid reacts chemically with an alkali?
What happens is that first if you put an acid indicator and a sulphuric acid it will turn red but if you add another solution it will turn a different colour. and if you add acid and alkali together then it will turn into salt and H2O xxx

What colour do you get when you add alkali to lithium?
green and this is definite because it came up in my GCSE's and i got it right

How do you make a homemade acid alkali indicator?
get some cabbage and crush it up get all the juice out and then pout in little tubes. add what chemicals you want to find out if thy are acid or alkali. the the colour will change and then you are going to have to find out what colour is what as i don't know! x]

You add UI to lemon juice what colour is the mixture?
The color will be a fairly strong red as it is a very strong acid in the pH scale.
How do you make water pH neutral?
* If the water is acidic add a bit of bicarb of soda * If the water is alkali add a drop of vinegar to your water filter You won't be able to taste these if you put them in in right quantities.
Is alkali soluble in water?
you can find out if a substance is an acid or alkali by adding universal indicator
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! :)
What colour will your pool water go if you add to much chlorine?
clear
