Which of the following statements about malonic acid is correct?
A
Malonic acid is a strong irritant and a corrosive.
B
Malonic acid is neither an irritant nor a corrosive.
C
Malonic acid is only a strong base.
D
Malonic acid is non-irritating and non-corrosive.
Verified step by step guidance1
Step 1: Understand the nature of malonic acid. Malonic acid is an organic compound with two carboxylic acid groups (-COOH), making it a dicarboxylic acid.
Step 2: Recall that carboxylic acids are generally acidic and can be irritants due to their ability to donate protons (H+), which can cause irritation or corrosion on contact with skin or tissues.
Step 3: Recognize that malonic acid is not a base; it is an acid, so statements claiming it is a strong base are incorrect.
Step 4: Consider safety data and chemical properties: malonic acid is known to be a strong irritant and corrosive because of its acidic nature and potential to cause chemical burns.
Step 5: Conclude that the correct statement is that malonic acid is a strong irritant and corrosive, while the other options contradict its chemical properties.
