Which of the following is a base? lemon juice stomach acid vinegar baking soda i think that it is vinegar

Hi there!

The correct answer is baking soda. This is how one can distinguish between either acids or bases.

Acids taste simply put, acidic. You know what I am taking about. They taste really sour. We know lemon juice tastes like this. Next, if it has the dead give-away in its name. Stomach acid, and vinegar (acetic acid).

Bases taste more bitter, and they are sometimes slippery. Baking soda on its own is very bitter.

I hope this helps now, and for any future issues you may have on this subject.
