Asked by Bob
I am stuck in the following in my homework.
BaC/2 and Na2CO3 turns different colors when the same indicator is added to each? Why does this happen? How is the ph of each of these different?
I have tried on this one and cannot get it. Thanks for our help.

What in the world is BaC/2? Could that be BaCl2? and Na2CO3.
BaCl2 is the salt of a strong base and a strong acid; therefore, the pH of the salt is neutral.
Na2CO3 is the salt of strong base and a weak acid; therefore the pH of the salt is basic.
In other terms which you may be studying (Bronsted-Lowry acids/baes).
Both Ba^2+ and Cl^- are weaker acid and base than water so the solution is neutral.
CO3^2- is a stronger base than H2O; therefore, the CO3^2- extracts a H^+ from H2O to form HCO3^- like this.
CO3^2- + HOH ==> HCO3^- + OH^-
That releases the OH^- and the solution is basic.
