Baking soda is also known as sodium bicarbonate. It is a more powerful leavening agent than baking powder. Baking powder is sodium bicarbonate + cream of tartar + starch.
I have to disagree that Baking Soda is a more powerful leavening agent than Baking Powder. Baking Soda begins it's leavening action almost immediately and is used greatly in many types of cookies that too much leavening would ruin. Baking Soda is a "single" action leavening agent while Baking Powder is generally a "Triple" Action leavening agent.
Baking Powder works in 3 stages (thus the term Triple Acting). The Sodium Bicarbonate is activated almost immediately in the recipe and begins the leavening of the product when liquid is added to the mixture. The Cream of Tartar that is in Baking Powder is activated by some type of "acidic" ingredient, this could be citrus, buttermilk, etc. The starch is then activated by "heat", once placed in the oven for baking and a certain temperature is reached, this activates the remaining leavening agent, creating the "third" stage and leavening the product to the maximum amount.
when baking powder combines with water, it turns into carbon dioxide which rises in the pastry, causing it to puff
Both baking powder and baking soda help cause batters to rise when baked.
There isn't one. Bread Soda is the Irish name for baking soda.

Yes, it could melt on ice.
Baking soda and baking powder are very different in how they work. Think of baking powder as making something more light and fluffy. Baking soda is going to make something taste less sweet and slightly more light. But yes. If your recipe calls for baking soda, or baking powder using the correct amount of both is important. You cannot substitute one for the other.
No. Baking powder is used to make floury things rise. Baking soda is used to add soda bubbles. But Baking Soda and Bicarbonate of Soda are the same thing.

If you do not have cream of tartar, baking powder will work just as well, or better. If the recipe calls for both cream of tartar and baking soda, leave out the soda if you use baking powder - it already has soda in it.
