Question

what do these data indicate about gastric juice?
it is very acidic.
it is very basic
it is neutral
it is dark red

Explanation:

Gastric juice has a pH of 1.7. A pH less than 7 indicates acidity. The lower the pH value, the more acidic the substance. Since 1.7 is much less than 7, it shows that gastric juice is very acidic. Also, the color change to dark red (a color associated with acidic indicators in some common pH - indicating systems) further supports this.

Answer:

It is very acidic.
