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.
Answer: Ethyl Ethanoate can be used as a developing solvent. It’s safer.
Explanation:Di ethyl ether should be carefully used because it’s highly flammable and intoxicating when inhaled and can cause explosions because of its high reactivity to air and light.
The molarity is a concentration unit which defined as the number of moles of solute divided by the number of liters of solution. So the molarity of the solution is 3/2=1.5 mol/L.
