Answer 1

Gastric Juice with a pH of about 1.5 is the most acidic among the given options.

Step-by-step explanation:

The most acidic substance among the given options is Gastric Juice with a pH of about 1.5. The pH scale measures the acidity or alkalinity of a substance and ranges from 0 to 14, where a pH below 7 indicates acidity. Gastric Juice is highly acidic due to the presence of hydrochloric acid (HCl) which aids in the digestion process in the stomach.

Lemon Juice is also acidic with a pH of about 2.3, but it is less acidic compared to Gastric Juice. Water and Blood have pH values around 7, which is considered neutral on the pH scale.
