Connie was making sodium chloride by adding an acid to an alkali. She followec I the progress of the reaction with a pH I sensor. At which pH would she know that the acid and alkali had completely reacted to give a salt solution?

Question

Connie was making sodium chloride by adding an acid to an alkali. She followec I the progress of the reaction with a pH I sensor. At which pH would she know that the acid and alkali had completely reacted to give a salt solution?

Answer 1

Hence, Connie would know that her reaction resulted in creating a salt solution when the pH sensor reads a value of 7.

Answer 2

Here we discuss the neutralization reaction which is the basis for titration methods in chemistry. It occurs when an acid and a base (or alkali, which is a specific type of base) react to form a salt, in this case sodium chloride (NaCI) and water.An acid has a pH level lower than 7 while a base has a pH greater than 7. By adding an acid to an alkali, they neutralize each other, which creates a substance with a balanced pH level.Connie is using a pH sensor, likely a device which directly displays the pH value as the reaction progresses. Since she wants to determine when the acid and the base (alkali) have completely reacted to form a salt, she will ideally reach a pH of 7 where the solution, now pure water and a salt, has a neutral pH.
