Which of the four basic substances on this ph scale is slightly basic?

1 answer:

6 0

The answer is B. The human blood of a healthy person should range between 7.35 and 7.45. This is slightly basic since neutral pH is usually 7.0. Calcium hydroxide is too basic (could go up to pH 12), while whole milk ranges at pH 6.5 and lemon juice is approximately of pH 2.2.
