Classify these substances as acidic, basic, or neutral:
vinegar, baking soda, tomato juice, sugar
a. vinegar - acidic
baking soda - basic
tomato juice - acidic
sugar - neutral
b. vinegar - basic
baking soda - neutral
tomato juice - basic
sugar - acidic
c. vinegar - neutral
baking soda - acidic
tomato juice - neutral
sugar - basic

I think the correct answer from the choices listed above is option A. The correct classification of the substances above would be:

Vinegar - acidic - it is acetic acid so it must be acidic
Baking soda - basic - it is sodium bicarbonate, a chemical with a basic (high) pH
Tomato juice - acidic - this juice contains some organic acids
Sugar - neutral - does not dissociates or contribute H+ or OH- ions to a solution

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
