Question

Ba(OH)4+NH4Cl--------->Bacl2+NH4OH


please balance this equation

with hit and error method full explanation
​

Answer 1

Ba(OH)2 + NH4Cl => BaCl2 + NH4OH

Above equation is unbalanced as no. of Hydroxide ions ( OH ) on Reactant side is 2 and On the product side , it is One...Also Chlorine atom is unbalanced on both sides...

First balance OH ions on both sides...Multiply 2 with NH4OH on the product side , we get the following equation.

Ba(OH)2 + NH4Cl => BaCl2 + 2 ×( NH4OH)

Now OH inos are balanced on both sides But NH4 and Chlorine gets unbalanced...in order to balanced simply multiply 2 with NH4Cl on reactant side...we get the following equation.

Ba(OH)2 + 2NH4Cl => BaCl2 + 2 NH4OH

Now above equation is balanced...

Note that the chemical formula of Barium hyroxide is Ba( OH )2 not Ba(OH)4 as you mentioned in your problem...
