You have been given two "mystery" solutions. Based on their properties, you must determine whether each is an acid or a base. Explain your reasoning for both solutions.

The first is a base, the second is an acid.

Explanation:

Bases are alkalis, so they will change red litmus paper to blue.

The second is an acid because it produces water when reacted with the alkali.

Example is HCL with NaOH. You will get NaCl and H2O.

another fact is it's sour.

i'm assuming that the correct answer is indeed the first one/ "a"..

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
