Solution
Ans 9 :
The reaction is called as neutralisation , or acid-base reaction , in which a salt is formed as the
major product and water is formed as the byproduct.
So the complete balanced reaction along with the products is given as :
NaOH (aq) + HC2H3O2 (aq) = CH3COONa (aq) + H2O (l)
Ans 10 :
Even here Al(OH)3 is base and H2SO4 is an acid.
The balanced reaction and its products is given as :
2Al(OH)3 (aq) + 3H2SO4 (aq) = Al2(SO4)3 (aq) + 6H2O (l)
