No, Soda Powder or Bicarbonate of Soda is a chemical leavening (lifting) agent that causes pastry and such to rise when baked and Baking Soda is just a less concentrated version that contains Bicarb of Soda.
Usually, yes. Many older recipes refer to baking soda as simply "soda". Typically, baking soda is used in very small amounts, so if the recipe calls for something like "1 tsp soda", it's a safe bet that they mean baking soda.
If the recipe calls for a soft drink, it will usually specify cola, lemon-lime, etc, and the amount will probably be larger, such as 1/2 cup.
No it doesn't, and never mix soda with baking soda and drink it it would be disgusting.
No, baking soda cannot substitute for baking soda because they are the same thing. Baking soda is just another name for sodium bicarbonate.
Helps Rise
Baking powder and baking soda are often used together in recipes in order to add lift to the final product. Because baking soda is a base and commercial baking powder is generally slightly acidic, they are often used together to neutralize both each other the other ingredients of the recipe. Yes baking powder and soda can both be used in the same recipe.
The recipe that I use calls for baking soda.
Well if your recipe calls for 1 teaspoon of baking soda, you would need four teaspoons of baking powder to produce the same amount of lift.
To replace for example 3 teaspoons of baking powder with baking soda, mix 1 teaspoon of baking soda with 2 teaspoons of cream of tartar.
Baking soda and eating soda are not the same. Baking soda is an ingredient that is found in baking recipes.
Heating the baking soda decomposes it, releasing CO2 gas, thus having the same effect as adding acid.
Yes it aids in the rising. When a recipe contains baking powder and baking soda, the baking powder does most of the leavening. The baking soda is added to neutralize the acids in the recipe plus to add tenderness and some leavening.
yes indeed
Baking powder is a mixture of baking soda, starch and an acid (often tartar) to activate the baking soda. Since baking soda is already in the baking powder, it is possible you will not need any additional baking soda. Baking powder and baking soda are used to "raise" or puff up the pastry - too little and it will not raise properly...too much and it will taste like soda. If you do not have a specific recipe, you will need to experiment.
No you Cant use Baking powder instead of bicarbonate of soda because if you put bicarbonate of soda into a cake mixture then you will get a very unpleasant taste !
