New process converts carbon into baking soda (2024)

How to convert carbon dioxide into baking soda? ›

But the change in chemistry also means that it could possibly be added to the sea. After the filter fills up with carbon dioxide, running seawater through the material creates another chemical reaction, producing sodium bicarbonate, or baking soda.

One method of turning carbon into baking soda is by mixing it with sodium hydroxide. This process results in baking soda, which can be used as a more renewable way of selling this product.

On being heated, baking soda undergoes decomposition to give sodium carbonate, water, and carbon dioxide. The reaction occurs as follows: 2NaHCO3(s)→Na2CO3(s)+H2O(g)+CO2(g)

Baking soda, or sodium bicarbonate (NaHCO3), is a chemical that can undergo a decomposition reaction when heated. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2).

The technology, also known as carbon capture, utilization and storage (CCUS), involves capturing CO2 from the chimneys of an industrial plant using chemical absorption.

For example, when leavening agents such as baker's yeast or baking soda are added to bread dough, they release CO2 which forms bubbles to give the dough the perfect consistency and structure for it to rise. CO2 creates the light and fluffy texture in baked goods by filling the batter with pockets of gas as it bakes.

The active ingredient in both baking soda and baking powder is sodium bicarbonate, or NaHCO₃. This compound acts as a leavening agent — which means that it reacts to release carbon dioxide gas (CO₂) which gives bread, cake, and pancakes that fluffy texture we know and love.

When you combine the solid (baking soda) and the liquid (vinegar), the chemical reaction creates a gas called carbon dioxide.

Thermal decomposition

At temperatures from 80–100 °C (176–212 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. The conversion is faster at 200 °C (392 °F): 2 NaHCO₃ → Na₂CO₃ + H₂O + CO. Most bicarbonates undergo this dehydration reaction.

A chemical reaction between the vinegar and the baking soda produces bubbles of carbon dioxide gas. The dish detergent in the vinegar helps the bubbles last longer than they would with just vinegar and baking soda.

What happens when you boil baking soda and water? ›

“When you add baking soda to boiling water, sodium bicarbonate breaks down into three compounds: sodium carbonate, water, and carbon dioxide,” says Sharma. “Sodium carbonate in water has a much higher pH than sodium bicarbonate [baking soda] in water, so that aids the pectin degradation.”

Placing baking soda in a hot oven will transform it from sodium bicarbonate into sodium carbonate, a stronger alkaline salt. By tracking the change in weight of the baking soda as it bakes, you will know when the transformation from sodium bicarbonate to sodium carbonate is complete.

The principle is that you can add lemon juice, vinegar, or citric acid to water, then pour a bit of baking soda in the container—and voilà! The acid in the water mixes with bicarbonate of soda (baking soda) to create carbon dioxide gas. The generated bubbles of CO2 make the drink fizzy.

Carbonic anhydrase (CA), the fastest enzyme that can covert carbon dioxide to bicarbonate, can be spontaneously entrapped in carboxylic acid group-functionalized mesoporous silica (HOOC-FMS) with super-high loading density (up to 0.5 mg of protein/mg of FMS) in sharp contrast to normal porous silica.

The breakthrough follows an almost centurylong effort to turn CO2 into a cheap, clean fuel. Researchers at the Massachusetts Institute of Technology exposed CO2 to catalysts and then electrolysis that turns the gas into a powder called sodium formate, which can be safely stored for decades.

Today, most commercial beers, soft drinks, seltzers and sparkling waters are created by “forced” carbonation. This is when manufacturers directly inject carbon dioxide into the beverage under high carbon dioxide pressures.
