Baking powder is Sodium Bicarbonate a polar compound that is particularly amenable to water (a polar solvent). So Baking powder will dissolve faster than a non-polar powder like Talcum powder. Also baking power is very finely ground and will present a large surface area to the water which hastens dissolving. Salt in comparison although a strongly polar compound is course ground and will take longer to dissolve.
it should dissolve 100% or it is probelematic
To dissolve flour you put HOT water and baking soda and leave it for about an hour and a half
White sugar is a dehydrated solid - all water has been removed from it. Brown sugar is already partly hydrated with molasses, so it already half way dissolved.

The proper substitution for baking powder is half baking soda and half cream of tartar. They both have leavening properties. If you don't have cream of tartar available, I guess I would go toward 2/3 - 3/4 baking soda and the rest cornstarch.
One to one and a half teaspoons of baking powder and a pinc to one half teaspoon of salt to a cup (125 g) of flour.
Substances dissolve more quickly when more surface area is exposed. By cutting an alka-seltzer in half, you are exposing more surface area to the solvent (water). It would dissolve even more quickly if it were cut into more pieces or crushed into a fine powder.
That would be a teaspoon and a half. Essentially, one teaspoon and half of another. Not one or two, but one and a half.
Although some recipes are quite sensitive, in most cases the difference between one half and one quarter teaspoon of baking powder would not be noticed.

Yes, of course! Otherwise everything would taste half as salty as it was supposed to.
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
