3.41 is the pH value of a sample that has ten times fewer hydronium ions than an equal volume of a vinegar sample with a pH value of 2.4.
Explanation:
pH of the first sample of acetic acid = 2.4
to know the [H+] concentration in the acetic acid solution, the equation used is:
pH = -log [H+]
[H+] = 
[H+] = 
[H+] = 3.98 X 
M
The concentration of H+ ion in first case is 3.98 X M, the second sample has ten times less hydronium ion so concentration of first case is divided by 10.
3.98 x 
M
Now pH of the sample having 10 times fewer ions of acetic acid:
pH = -log [H+]
putting the values in the above equation:
pH = -log [3.98 x M]
pH = 3.41
If solution has ten times less hydronium ion the pH will change to 3.41.
Answer:
oh I'm here thanks for your points
Answer:
number of individuals
Explanation:
calculated by dividing the number of people by area
Answer:
I think you are correct with your answer.
Explanation:
But I don't think that the explanation is correct because I think that it is the formation of both baking soda and water that makes it work...Vinegar doesn't make gas bubbles maybe because it hasn't reacted or maybe because it is not the right ingredient for the solution you are looking for. Thank you for the question.....Am not sure I really helped in your question but thank you..
Lol I don’t know anything about this sorry
