Is soil an acid or alkali?
acid
When an acid and an alkali react it is called combustion?
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
What gas is given off when acid reacts with a alkali?
Depends on the acid and alkali. But in most cases Hydrogen or Carbon Dioxide.
What happens when an acid reacts with an alkali?
Acid + alkali ---> Salt + Water for exampleSodium Hydroxide + Hydrochloric Acid ---> Sodium Chloride + Water
Is sulfur dioxide an acid neutral or alkali?
It is a quite strong acid
What is a indicator of acid and alkali?
acid should be a bright pink colour when using the indicator and alkali should go a greeny colour :) hope this helped you
What are the names of plants that can be used as indicators of acid and alkali?
What are the names of plants that can be used as indicator of acid and alkali
How does a acid-alkali indicator indicates?
The pH of a solution.
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 colour will universal indicator turn when acid is mixed with alkali?
It will turn green! :)
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 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.
Does an alkali substance neutralize an acid?
no it doesn't, it simply just turns it into an indicator and has not neutralised it.
How could you test for an acid or alkali?
Litmus; universal indicator; reaction tests; spectroscopy.

What would you mix an alkali or acid with to get a coloured substaince?
You could mix an acid or alkali with an indicator such as methyl orange or phenolphthalein. Phenolphthalein is colorless in an acidic medium and pink in an alkaline one.
What would be the reaction of a litmus paper to an acid?
It turns red, alkali will turn it blue. A better alternative would be the univerasal indicator which also shows how strong/weak the acid/alkali is
