Bicarbonate Soda vs. Baking Soda: Clearing Up the Confusion

Same Name, Same Stuff

There’s a lot of talk online about bicarb. It’s on recipe blogs, cleaning forums, and health advice pages. People keep asking if bicarbonate of soda is the same as baking soda. In my kitchen, there’s just one tub with a big label: “baking soda.” My mother called it bicarbonate of soda and used it for just about everything — brushing her teeth, making fluffy pancakes, and even tackling stubborn stains on kitchen counters. The truth is, there’s no difference. Both names point to one simple white powder: sodium bicarbonate.

Why All The Names?

This mix-up comes from location and tradition. Folks in the United States stick with “baking soda.” Across the UK, Australia, and much of Europe, "bicarbonate of soda" or just "bicarb" is the go-to name. Grocery stores know this, so they label it to match the taste of their shoppers. The contents never change. One ingredient, many uses, many names.

One Ingredient, Many Uses

Most people know about baking soda from the kitchen. That box in your pantry works its magic in cakes. Stirred into batter and hit with something acidic like lemon juice or buttermilk, it starts to fizz. That fizz is carbon dioxide gas, lifting up your cake. There’s a reason scientists and chefs both trust sodium bicarbonate for these reactions — it works every time. According to the U.S. National Library of Medicine, sodium bicarbonate’s chemical formula, NaHCO₃, never changes whether you find it in North America or Europe.

Beyond cooking, households rely on this powder for fresh-smelling refrigerators and scoured sinks. Its gentle abrasion knocks away dirt without scratching pots or stove surfaces. Pull out your chemistry hat, and the stuff neutralizes both mild acids and bases, which explains why it calms heartburn just as easily as it removes a coffee stain. Many parents keep a box handy for mild insect bites — sprinkle it in bath water and it soothes itching skin.

Fake News and Real Risks

Misinformation circles fast, especially when health remedies trend on TikTok and YouTube. Some content creators claim that baking soda and bicarbonate of soda have different levels of “strength” or “purity.” That myth fuels confusion and, sometimes, price gouging. Pharmacies and supermarkets sell them side by side, but the label and packaging color drive prices up for no scientific reason. The U.S. Food and Drug Administration lists sodium bicarbonate as “generally recognized as safe” when used as directed. Both your classic yellow Arm & Hammer box and a pricier “bicarbonate of soda” jar offer the same safety profile.

How to Get the Most Out of It

Some families buy separate boxes for baking and cleaning. Marketing nudges us to believe that one is purer. For most kitchen and cleaning tasks, the regular stuff works just fine. If you look at product websites and official factsheets, the product stays chemically identical for both culinary and household versions. If you want to avoid aluminum compounds, keep an eye out for “baking powder” — separate from baking soda — since that’s where additives come in.

In my home, baking soda under all its names remains a workhorse. Every time I see two boxes on the store shelf, priced differently just for the label, I skip the hype and grab the one that matches the recipe, the cleaning tip, or my mom’s old habits. It’s sodium bicarbonate, plain and simple — a friend in every cupboard, no matter what the package says.
