Each of the following mixtures is placed in a dialyzing bag and immersed in distilled water. Circle the substances that will be found outside the bag in the distilled water.
a. KCl solution and glucose solution
b. albumin solution (colloid)
c. albumin solution (colloid), KCl, solution, and glucose solution.
d. urea solution and NaCl solution.
the colloids wont pass thru. Urea and glucose will as will the salt ions.
"MathMate", thank you for your help, but in the future please use a different pen name to avoid confusion with that of an existing tutor.
Wow! How weird is the impostor to use "wont" and "thru" and no capital letter at the beginning of the first sentence!! Complete give-aways!! <shaking my head>
I have had the same experience but I signed in with a program generated by Leo and I understand that it is now harder for imposters to use my name with an answer. I haven't had the problem since I signed on with that program. Writeacher has done the same.
To determine which substances will be found outside the dialyzing bag in the distilled water, we need to understand the process of dialysis.
Dialysis is a process that uses a semipermeable membrane to separate substances based on their molecular sizes. Only small molecules, ions, and water can pass through the membrane, while larger molecules such as proteins and colloids are unable to cross.
Now let's analyze each mixture and identify the substances that will be found outside the dialyzing bag in the distilled water:
a. KCl solution and glucose solution:
KCl and glucose are both small molecules and can pass through the dialyzing bag. Therefore, both substances will be found outside the bag in the distilled water.
b. Albumin solution (colloid):
Colloids like albumin are larger molecules and cannot pass through the dialyzing bag. Hence, the albumin solution will stay inside the bag, and no substances will be found outside in the distilled water.
c. Albumin solution (colloid), KCl solution, and glucose solution:
Similar to the previous case, the albumin solution (colloid) will remain inside the bag since it cannot cross the dialyzing membrane. However, both KCl and glucose are small molecules and will be able to pass through the membrane, so they will be found outside the bag in the distilled water.
d. Urea solution and NaCl solution:
Urea and NaCl are small molecules that can diffuse through the dialyzing bag. Therefore, both substances will be found outside the bag in the distilled water.
In summary, the substances that will be found outside the dialyzing bag in the distilled water are:
a. KCl and glucose in mixture a.
c. KCl and glucose in mixture c.
d. Urea and NaCl in mixture d.
