Answer to Question #282693 in General Chemistry for zmo

Question

what volume (ml) of 0.500M HCL is needed to neutralize 16.00mL of 0.200M Ba(OH)2 ?

Answer 1

HCl is a monoprotic acid (1 H⁺) and Ba(OH)₂ has 2 OH^- groups, so it will take TWO HCl to neutralize ONE Ba(OH)₂.

The balanced molecular equation for this reaction is:

2HCl(aq) + Ba(OH)₂(aq) ===> BaCl₂(aq) + 2H₂O(l)
