Answer:
Bottle 2 shows the vinegar has a molarity of 2M acetic acid
Explanation:
2M of acetic acid has higher concentration of acetic acid as compared to other vinegar. In 2M of acetic acid is equals to 120 gram of acetic acid in 500 ml of water which is quiet higher than other concentration of acetic acid in vinegar which is 4%. So Mr. Holmes has to use 2M of acetic acid which will produced high intense eruption in the volcano and win the national science fair contest.
Answer:
The pH is 11
Explanation:
Because pH + pOH = 14
and pOH = - log [OH⁻] = - log (1 x 10⁻³) = 3
we can now calculate pH by manipulating equation one above
pH = 14 - pOH = 14 - 3 = 11
Thus the pH of the solution is 11
