it makes it more acidic, using buttermilk isn't critical, you can just use ordinary milk but if you want a substitute you could always use milk and a little bit of vinegar.
Mainly for flavor, it has a higher fat content so the texture will be a little heavier than with regular milk.
you can, but the resulting muffin will not have as fluffy nor as moist a texture... the buttermilk's acidity is higher than that of regular milk, too, so the flavor will be a little different. so all in all, major differences after baking would be first and foremost texture, and second, flavor.
If it has a greater concentration, it will be considered more basic or alkaline. So, with a higher concentration, you will not need as much baking soda in your neutralization reaction.
YesCultured Buttermilk is low in fat.Also, people who are lactose intolerant sometime tolerate cultured buttermilk because some of the lactose is fermented by bacteria during the creation process.Due to the higher acidity level in cultured buttermilk, it has a slightly sour taste, but has a longer shelf life in the refrigerator.Even if you don't like how it tastes, try substituting it for regular milk in baking. It can add a small lemony taste in things (like crepes or pies). It will even keep your blueberries blue, when you make blueberry muffins.
Only after weighing the objects.
Baking Soda has a higher desity.
alka seltzer it has this bubbly stuff that makes it erupt higher than baking soda.
I think if you change the baking soda the rocket will explode higher
In chemistry baking soda has a pH value higher than 7 and reacts with acids.
Na have higher shielding effect than Li *According to my chemistry book
Definitly nubian it is MUCH higher in buttermilk fat content
soap, baking soda
