Question

During an autopsy, the pH of a man’s stomach was measured to be at 8.3. Was this abnormal or normal? If abnormal, what might this person have ingested before death?
Question 16 options:

Abnormal, battery acid


Normal


Abnormal, bleach


Abnormal, lemon juice

Answer 1

Answer: Abnormal, bleach

It is considered to be abnormal and it can be deduced by the PH of 8.3 to be bleach, because the normal PH of the stomach is approximately between 1.5 to 3.5. The PH value of lemon juice is found to be 2, whilst the PH of battery acid is 0.

However Bleach is made up of Sodium hypochlorite, it is commonly found in every household for the purpose of washing clothes and its PH value is approximately 12 which makes it highly alkaline, which makes it clear that Abnormal, bleach is the correct answer
