I believe the answer is B!
H2SO3 or sulfurous acid is actually a strong acid. We know
for a fact that strong acids completely dissociate into its component ions in a
solution, that is:
<span>H2SO3 --> 2H+ + SO3-</span>
<span>So from the equation above, there are 2 moles of H+</span>
Answer:
if charge of ion is positive then it will loose electron
if charge of ion is negative it will gain electron
