Salts cause acidity

Postby Jordan_Wesson_2J » Mon Dec 03, 2018 4:34 pm

How do you know when adding a salt can cause it to become more acidic? why doesn't NaCl do this?

If one of the ions in the salt is also an acid, then when the salt is added to water, the acidic ion will also react with the water. NaCl doesn't do this because neither Na+ or Cl- are acidic. Professor Lavelle used the example NH4Cl in class to demonstrate this to us because the NH4+ ion is acidic in nature and will readily give up a proton to the nearby water molecules.

NaCl interacts with water, because the polar nature of water, however, it does not pull a hydrogen ion off of the water molecule, like an acidic salt would do.

There has to be a proton (aka hydrogen) that can be pulled off the acid and create a H3O+ ion to increase the acidity of the solution.
