Question

You have been contracted to determine how different salts affect the pH of water. Which of the solids in the following set should you test to investigate for the effects of cations on pH?
a. AlBr3
b. Rb2SO3
c. MgCl2
d. RbBrO
e. CH3NH3Br

Answer 1

Answer:

Hence the solids that should test to investigate the effects of cations on pH is

$AlBr_{3}$ (Cation is Al 3+)  

$MgCl_{2}$  ( Cation is Mg 2+)  

$CH_{3} NH_{3} Br$ ( Cation is NH2+).

Explanation:

The solids in the following should you test to investigate the effects of cations on pH.  

$AlBr_{3}$ contains (Cation is Al 3+)  

$MgCl_{2}$ contains ( Cation is Mg 2+)  

$CH_{3} NH_{3} Br$ contains( Cation is NH2+ )
