Question from Barbara
Is Arm and Hammer Super Washing Soda the same as Arm and Hammmer Baking Soda just in a bigger box ?
Baking soda is sodium bicarbonate and washing soda is sodium carbonate. They are very similar, but different.
Sodium carbonate (also known as washing soda or soda ash) has the chemical formula Na2CO3. It most commonly occurs as a crystalline substance, which can be extracted from the ashes of many plants. It is synthetically produced in large quantities from table salt in a process known as the Solvay process.
Sodium bicarbonate has the formula NaHCO3. It is commonly called sodium hydrogencarbonate, sodium bicarb, baking soda, bread soda, cooking soda, bicarb soda, saleratus or bicarbonate of soda. It is a component of the mineral natron and is found dissolved in many mineral springs. The natural mineral form is known as nahcolite.
