Chemistry HW for class

Question

Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction.

CsBr

Answer 1

It seems you are asking several questions of the same type. I answered your first one, and I'll answer this in the hope you can do the others. One easy way to tell if a salt is neutral acidic or basic, is to look to see how it was formed.

If formed from a STRONG ACID + STRONG BASE ==> neutral salt

If formed from a STRONG ACID + weak base ==> acidic salt

If formed from STRONG BASE + weak acid ==> basic salt

If formed from weak acid + weak base ==> more difficult to determine and must look at Ka and Kb values

CsBr is formed formed from a STRONG BASE (CsOH) and a STRONG ACID (HBr). So CsBr is a NEUTRAL salt.

CsOH + HBr ==> CsBr + H2O
