Hòa tan kim loại natri trong nước sản phẩm sau phản ứng là dung dịch NaOH và có khí H2 thoát ra.
Sau đó sục khí CO2 qua dung dịch NaOH thu được sản phẩm là muối Na2CO3.
Tiếp tục cho Na2CO3 tác dụng với axit H2SO4 sản phẩm tạo thành là muối natri sunfat.
Cho muối natri sunfat tác dụng với BaCl2 sau phản ứng có hiện tượng kết tủa trắng là BaSO4.
