What is baking soda?

[UsedToBeAPaxmanFan]

Hi
I have a recipe I want to try out but it's from an American website and requires two teaspoons of "baking soda". I do know whether this equates to UK baking powder or if it means bicarbonate of soda. I've tried Googling but am no wiser.

Any ideas?

Don't know, not do know!

I googled it and the top hit said they were the same.

AFAIK baking soda is bicarbonate of soda and Waitrose agrees with me so I am sticking with it

Thanks for your answers. I was guessing from the recipe that it was more likely to be baling powder so I'm glad I asked.
