What do indicators test for?
Indicators are used to test if something for example whether vinegar is an acid or alkali. Due to the pH scale, 1 - 3 is a strong acid, 4 - 6 is a weak acid, 7 is neutral, 8 - 10 is a weak alkali and 11 - 14 is a strong alkali. Vinegar should turn orange when added with an indicator, with the pH of about 3.
What is an organ containing a strong acid?
The stomach contains strong acids that are used together with enzymes to digest food.
Why is it that nitric acid is used in gmelin's test?
it acts as oxidizing agent.
Can concentrated nitric acid be used in flame test instead of concentrated hydrochloric acid?
Cleaning of the test wire (platinum or nickel-chromium alloy) may by realized with nitric acid or hydrochloric acid.Rinsing is made with demineralized water.
What structure liquefies foods using acids and begins protein digestion?
The name of that structure is stomach. Your stomach starts to digest the food. So the food becomes more liquid. It uses very strong acid for this purpose. The acid is hydrochloric acid. It is wonderful to have such strong acid to be used in your body.
Indicators used in acid base titration?
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
Which indicator is used in titration for strong acid?
It depends on the base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator.
What is an battery acid?

Why acetic acid is used in fouchet test?

What substances have a strong acid in them?
A single substance will not have an acid 'in' it, but it can be an acid. The hydrochloric acid in our stomachs is a strong acid. Other examples are sulfuric acid (in wet batteries) and nitric acid which is used to make fertilizers and dyes.
What is the strong acid that is used in many experiments?
sulfuric acid (h2so4) and hydrochloric acid (HCl)
What is phenolphthalein used in titration labs?
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.
What is Ph level testing used for?
