Why ammonia is used in iron limit test?
purple colour of ferrous thioglycolate is formed only when alkaline medium is maintained, it can be done by using dil.ammonia in presence of citric acid.
What is the difference between Benedict's solution and fehling's solution?
Fehling's test uses tartaric acid, and Benedict's test uses citric acid
Give reason use of ammonia in limit test of iron?
Ammonia is limit test of iron because it is a chemical. Ammonia is a very story chemical.
What chemical test is used to measure citric acid content in drinks?
Some methods are: absorption spectrophotometry, amperometry, titration with NaOH.
Why can you not test solid citric acid on dry pH paper?
Acids show their behaviour only when dissolved in water. This is because the H+ ions in water cant exist as such. They mix with water to form Hydronium ions and these are responsible for the acidic nature. As neither solid citric acid not dry ph paper contain water u cant test them that way
Why Citric acid use in limit test for iron?
It forms a complex with iron which prevents the precipitation of ferrous or ferric hydroxide after the addition of ammonia to make the solution alkaline

Can colorimetry be used to test concentration of citric acid?
It can be if you can convert the citric acid to a chromophore, i.e., something that is colored. Otherwise, you cannot.

Why is it that when iron is added to dilute acid the test tube turns hot?
Because there's a chemical reaction going on.
