Which solution has a pH that is closest to neutral? (1 point) A. hand soap

B. milk

C. saliva

D. chicken soup​

Remember, a pH of 7.0 is neutral. Anything above that (7–14) is basic, and anything below that (0–6) is acidic. pH of hand soap is in the range 9-10, but as natural pH of skin is slightly acidic (around pH 5) such soap lefts skin dry and rough, thus more and more soap producers modify their recipes to lower soap pH.milk has a pH of around 6.5 to 6.7, which makes it slightly acidic. Some sources cite milk as being neutral since it is so close to the neutral pH of 7.0. However, milk contains lactic acid, which is a hydrogen donor or proton donor.Saliva has a pH normal range of 6.2-7.6 with 6.7 being the average pH. Resting pH of mouth does not fall below 6.3. In the oral cavity, the pH is maintained near neutrality (6.7-7.3) by saliva.The pH level of 0.25L of chicken soup is 5.80.
