Question

question 11 (2 points)
what kind of solution causes cremation to happen to to red blood cells: isotonic, hypertonic, or hypotonic?
isotonic
hypotonic
hypertonic
question 12 (2 points)
if a solution has more hydrogen ions h+ than hydroxide ions oh- is the solution acidic or basic?
acidic
basic
neither

Explanation:

For Question 11, in a hypertonic solution, water moves out of red - blood cells due to osmosis, causing them to shrink (cremate). In isotonic solutions, there is no net water movement, and in hypotonic solutions, water moves into the cells causing them to swell.
For Question 12, by definition, a solution with more hydrogen ions ($H^+$) than hydroxide ions ($OH^-$) is acidic. A basic solution has more $OH^-$ than $H^+$, and a neutral solution has equal amounts.

Answer:

Question 11: C. Hypertonic
Question 12: A. Acidic
