Which statement is true regarding a titration? it measures the amount of heat given off in combustion reactions. it determines how much water to add in a dilution. it determines the concentration of an unknown substance in neutralization reactions. it determines if a reaction will take place in single replacement reactions. it is used to make a solution of designated molarity.

 It determines the concentration of an unknown substance in neutralization reactions.

Explanation: Titration is defined as the process where a solution of known concentration is used to determine the concentration of an unknown solution.

Volumetric titrations are usually used for neutralization reactions.

When an acid and base reacts to give salt and water, the reaction is called as  neutralization reaction.

The normality equation used during the titration is:

= Normality of acid solution

= volume of acid solution

= Normality of basic solution

= Volume of basic solution

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
