Question

Am solution of the ionic salt NH4CIO4 would have (?) pH.

A. a neutral
B. an acidic
C. a basic

Answer 1

an acidic pH

Step-by-step explanation:

Remember that a strong base and a strong acid make a neutral* salt,
a strong base and a weak acid makes a weakly basic salt,
a weak base and a strong acid makes a weakly acidic salt.

NH4ClO4 is a salt made from NH3 and HClO4,
or a weak base and a strong acid, so thus NH4ClO4 is weakly acidic
