Acid turns blue litmus

Which of the following is a strong acid?
Sulphuric acid is a strong acid because it is mineral acid and dissociate completely into ions.
Which gas is released when acid reacts with metals?
Hydrogen gas is formed as the metal reacts with the acid to form a salt. Many, but not all, metals react with acids. Hydrogen gas is formed as the metal reacts with the acid to form a salt.
Acid present in soured curd is
Lactic Acid is present in sour milk or curd.
The increased acidity causes the milk proteins (casein) to tangle into strong masses or curds. Milk that has been left to acid (crude milk alone or purified milk with included lactic acid bacteria) will likewise actually deliver curds, and sour milk cheeses are created along these lines.
Sour Tasting milk items, similar to yogurt, buttermilk, and so on created sour taste as the milk is refined with lactic acid bacteria. The grow, use the lactose to deliver mostly lactic acid. The acrid taste is because of lactic acid is present in the product.

Reaction between acid and base to form salt is called
The reaction between acid and base to form salt and water is called neutralisation reaction.
Which of the following does not form an acidic salt?
Carbonic acid is a weak acid. Strong acids make acidic salts with weak bases and neutral salts with strong bases while weak acids make basic salts with strong bases and neutral with weak bases.
