No, if you use baking powder to replace the baking soda it will alter the dish you are cooking. In cookies, baking soda makes for crispier cookies, and baking powder makes softer cookies. But, no they aren't interchangeable.
The short answer: no, there's no substitute, and yes, baking soda is necessary. Baking soda, also known as sodium bicarbonate, has a number of functions in baking - it acts as a leavener, as well, as a browning agent. What does that mean? Think about a slice of bread: it's full of little holes and pockets; and, it's not a perfectly smooth, flat surface. Those holes and pockets are caused by carbon dioxide, which baking soda gives off when it reacts with an acid. Remember those baking soda-and-vinegar volcanoes from science class? This is essentially the same thing. Baking soda, when it reacts with an acidic component in a recipe, fizzes and bubbles, creating an airier, lighter-textured bread than otherwise. However, there is such a thing as too much baking soda. If a baked good turns out dense and leaden, it's quite possible that excessive baking soda was the culprit. Why? If too much carbon dioxide is produced, the bubbles rise to the top of the bread and burst, instead of hanging out in the middle and making the bread airier.
Baking soda's other job is to help browning by neutralizing the natural acidity present in food. If you see a recipe with a disparately large quantity of baking soda relative to the flour (the average ratio is 1/4 teaspoon per cup of flour), it's probably used to neutralize the acid and aid browning.
Baking powder is similar to baking soda, though it's about a quarter as strong, and it's mixed together with exactly the right proportion of acid in order for it to activate. Though it may seem counterintuitive when a recipe calls for both, it makes scientific sense.

For some recipes you can replace it with baking powder.

No; they are very different. Baking Soda is a leavening agent, salt is a mineral that enhances flavor, the two are definitely NOT interchangeable.
Probably not. Baking mix has other ingredients such as baking soda/powder and dried milk or eggs. What type of baking mix is it and what are you making? If you're just battering something it will be fine, but if you're baking something, not so much.
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.

Something baby!
Baking soda and eating soda are not the same. Baking soda is an ingredient that is found in baking recipes.

Not to bake stuff like bread. You can substitute 1 baking soda for 2 baking flour to make reductions. You can substitute 1 baking soda for 1 baking flour for gags (throwing on someone in the shower).
There isn't one. Bread Soda is the Irish name for baking soda.
