Study guide question

Postby 205150314 » Wed Mar 11, 2020 1:54 pm

What does the professor mean on his powerpoint for the final by "IF IT IS A SALT WITH A BASIC ANION, THEN pH > 7 AND CALCULATE [OH¯]
THEN USE pH + pOH = 14.00 TO CALCULATE pH"

If the salt contains a basic anion, the dissociation will thus produce OH- instead of H3O+ so you need to use your ice table to find [OH-] and then find pOH.. then convert pOH to pH using the equation pH + pOH = 14

The basic anion will cause the dissociated solution to produce OH-. In this case, basic is the opposite of acidic, not taken to mean 'elementary'
