Sodium bicarbonate is formed from soda ash that occurs naturally in our environment. The ash is mined and processed to resemble the fine white powder we know as baking soda. This hard-working alkaline mineral is an astounding multi-purpose product due to its chemical and physical properties.
Baking soda, dates back to the Egyptians, who used it both as a soap-like cleaning agent and in mummification.
In 1843, Alfred Bird, a British chemist produced a modern, improved version of baking soda to enable him to bake yeast-free bread for his wife Elizabeth, who suffered with allergies to eggs and yeast. This lead to Bird eventually receiving an order to supply the British Forces with his baking soda, which was used not only in the baking of fresh bread for the troops, but also in hospitals to supply the sick and wounded with cakes and puddings.
In 1846 it was branded and sold by the company Arm & Hammer; however it wasn’t until 1927 that it began to be promoted for its extraordinary benefits in the home.
In 1970 Arm and Hammer sponsored the very first Earth Day; this is when the humble baking soda gained its worthy attention as an eco-friendly alternative to conventional chemical cleaners.
By 1972 it had a new widespread following: an open box of baking soda could be found in the fridges of almost every household, keeping the food fresh and the fridge deodorised.
In 1986, the Statue of Liberty was cleaned and restored ahead of its 100th birthday, using only baking soda, leaving its inner copper walls undamaged and pristine.
Today this adaptable all-rounder can be found in almost every home. Along with its success in the kitchen, it is an important ingredient in toothpaste, cat litter, deodorant and antacid tablets and is the main component in fire extinguishers. This resourceful product is probably one of the most important natural green cleaning ingredients available. It is extremely alkaline with bactericidal and stain-removing properties, and is particularly renowned for absorbing grease and spills, and neutralising food, pet, smoke and stale odours around the home. Baking soda also makes an effective scrub for cleaning tough stains and blemishes from work surfaces while being gentle enough not to scratch.
Note: When baking soda is mixed with vinegar and lemon, the solution bubbles and effervesces. This is quite normal and results from the acetic acid in the vinegar and lemon reacting with the sodium bicarbonate, a compound in baking soda. This process forms carbonic acid, which is unstable, and immediately falls apart into carbon dioxide and water. The bubbles you see from the reaction come from the carbon dioxide escaping the solution that is left.
