Question

1. in terms of ph, explain what would happen if you mixed vinegar with a solution of ammonia? the ph scale oa) the ph level of the solution would be less than 3 ob) the substances would not mix, and you could still take two different ph readings oc) the ph level of the solution would be more than 12 od) the ph level of the solution would be between 3 and 11 12) use the ph scale to compare an apple and a lemon. the ph scale oa) the lemon has a higher ph than the apple. ob) the lemon has a lower ph than the apple. oc) the apple has a lower ph than the lemon. od) the apple and lemon have the same ph level.

Explanation:

1. Vinegar is acidic (pH around 2 - 3) and ammonia is basic (pH around 11 - 12). When they react, they neutralize each other. The resulting solution's pH will be between the pH values of the two reactants, so between 3 and 11.
2. Lemons are more acidic than apples. On the pH scale, more acidic substances have lower pH values. So the lemon has a lower pH than the apple.

Answer:

1. D. the pH level of the solution would be between 3 and 11
2. B. The lemon has a lower pH than the apple.
