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.
baking soda is a mixture of Cream of tartar and bicrabonate of soda. i belive the ratio is 1:2 (in the order above). but buying baking powder will make the dish more consistent with the recipie.
These two are different. You can not replace one with another.
You should use the amount that the recipe calls for. Usually it is a teaspoon or two.
You Can not substitute them. Baking soda and baking powder are two separate items that are not the same.

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.
You can use cream of tartar and baking soda as a replacement for baking powder. One half teaspoon of cream of tartar and one quarter teaspoon of baking soda will equal one teaspoon of baking powder.
I have been informed that baking powder is 1/4 baking soda & 5/8 cream of tartar the rest being made up of various other ingredients. Baking soda by itself is no good as it is alkaline and you need an acid so, depending on the recipe, you could try lemon juice, white vinegar or buttermilk.

There are approximately 2g of carbohydrates in 1 teaspoon of baking powder. These mostly come from the starch (often cornstarch) put into baking powders to stop them from clumping. You can make a low carb version using the following conversion: 1 teaspoon of baking powder = 1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar.
If you are using it as a levening agent, you can substitute baking powder. One teaspoon of baking powder replaces 1/3 tsp of baking soda AND 2/3 tsp cream of tartar.
HOMEMADE SUBSTITUTE FOR BAKING POWDER 2 tbsp. cream of tartar 1 tbsp. baking soda 1 tbsp. cornstarch Sift together. Store in airtight container. One teaspoon of this is equal to 1 teaspoon store bought baking powder. Source: www.cooks.com Baking powder has two active ingredients: Cream of tartar (tartaric acid) and baking soda (sodium bicarbonate). The reaction of these two creates a salt and a gas, (carbon dioxide) which, as it is larger in volume than the original ingredients, causes the food to fluff up, rise etc. If the other ingredients in the recipe include an acid (say milk which has lactic acid) then the cream of tartar can be reduced or eliminated, as the baking soda will react with any acid. It is important to get the proportions correct or there can be not enough rising or a bad tasting result! If too much of baking powder is used the resultant salt will also affect the taste of the food. Other methods of creating lightening or rising involve incorporating air in the food that will expand during the cooking process, (beating and folding), or adding yeast that as is grows, exhales gas, (carbon dioxide again) creating more of those useful bubbles. Foods that use rising require binders such as proteins, (examples are the gluten in some flours and the protein in egg whites,) as these are elastic enough to stop the bubbles bursting, but are fixed when dried out enough and the baking is complete. That is why a cake or souffle will fall or flop if removed from the oven before it is done: the bubbles are still elastic and can be broken.
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.
You can add some baking powder, but it's not an ideal substitute; baking powder is a mixture of bicarbonate of soda (baking soda) and cream of tartar. This means you need to add slightly more than is baking powder than the quantity suggested for baking soda; usually around 1/4 teaspoon on top of the quantity suggested for bicarb.
Yes, you can. Substitue 1/2 teaspoon of cream of tartar plus 1/4 teaspoon baking soda for 1 teaspoon of baking powder. Source: Emergency Substitutions. Better Homes and Gardens New Cookbook. Des Moines, Ia: Better Homes and Gardens Books, 1999.
They won't come out crisp. Cream of Tartar is used for a variety of things in different recipes. For cookies, you should be able to substitute baking powder and get the same result.
Actually baking powder can be made by combining 1 part baking soda and 3 parts cream of tartar. This information comes from the recipe book called:"What's Cooking"
