Acids naturally present in food are safe to eat because they usually are

This question is not complete but the completed question is below

Acids naturally present in food are safe to eat because they usually are

A. Weak

B. concentrated

C. dilute

D. strong

The correct option is A.

Explanation:

Acids that are naturally found in food are organic acids. Organic acids are generally known to be weak acids. An acid is a substance that produces hydrogen ion or hydroxonium ion when dissolved in water.

A weak acid however ionizes partially (not releasing all its possible hydrogen ions) in water. Weak acids have pH that are close to neutral (pH 7) and hence are safe for consumption.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
