Does the addition of a small quantity of dilute solution to a large quantity of concentrated solution change the molarity of the concentrated solution? What about the reverse with a small amount of concentrated to a large amount of dilute?
Homework Answers
dilution is increases the concentration of solution is decreases
The addition of a small quantity of dilute solution to a large quantity of concentrated solution NO change in the molarity of the concentrated solution Because of concentration is large compared to the solution .The small dilution is negligible.
NO change in molarity
The addition of a large quantity of dilute solution to a small quantity of concentrated solution decreases the molarity of the concentrated solution. Because of dilution is large compared to cocnetration.
The molarity of solution is decreases

Addition of phenolphthalein to an unknown colorless solution does not cause a color change. The addition of bromthymol blue to the same solution leads to a yellow color. Is the solution acidic, neutral, or basic? Which of the following can you establish about the solution: What other indicator or indicators would you want to use to determine the pH of the solution more precisely?

What is the main property of a buffer solution? A buffer does not allow any change in pH. A buffer resists drastic changes in pH upon addition of acid or base. Buffer solutions have an unlimited capacity to resist pH change. Upon adding a small amount of a strong acid or strong base, a buffer increases the change in pH to a very large amount
