Answer : The pH of the resulting solution is 4.6
Explanation : Given,
Activity coefficient for acetic acid = 1.000
Activity coefficient for acetate ion = 0.775
Ionic strength = 0.10 M
To calculate the pH of resulting solution we are using Henderson Hesselbach equation :
![pH=pK_a+\log \frac{[Salt]}{[Acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%20%5Cfrac%7B%5BSalt%5D%7D%7B%5BAcid%5D%7D)
Now put all the given values in this expression, we get:
Thus, the pH of the resulting solution is 4.6
Answer:
A GALAXY WIITH I YHINK MANY
Explanation:
Answer:
C. Water will move from solution A to solution B because glucose is in higher concentration.
Explanation:
In osmosis, the molecules of solvent will pass through a semipermeable membrane from a less concentrated to a more concentrated solution.
Solution B is more concentrated, so the water will move from A to B.
A and D are wrong, because the size of the solute particles does not control the direction of osmosis.
B is wrong because water moves to the more concentrated solution.
Answer:
Distillation
Explanation:
Distillation is the process of separating the components of a liquid by using the method of selective boiling and condensation.
Since the components of the liquid have different boiling points, they would evaporate at different temperatures, thus causing the separation to occur.
So, distillation can be used to separate a mixture of milk and water.
Answer:
has two double C-C bonds
Explanation:
A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon.
If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.
