Interpretation:
The statements about the general properties of solutions are true or false has to be identified.
Concept introduction:
Solution: It is the homogeneous mixture of two or more substances. In such a mixture, solute is a substance (of lower proportion) dissolved in another substance (of larger proportion), called solvent. In aqueous solution, the solvent is water.
Homogeneous mixture:
- It is a mixture in which the components are uniformly distributed throughout the mixture.
- There is only one phase of matter observed in a homogeneous matter.
- Example- Air, Sugar water , Rain water
Explanation of Solution
Reason for true statements:
Option a):
In a solution, more than one substance can dissolve in a given solvent.
Hence, the statement is true.
Option b):
A solution is formed by dissolving two or more substances in a solvent. In a solution, the components are distributed uniformly through-out and hence it is homogeneous.
Hence, it is true.
Option c):
In a solution, the components are distributed uniformly throughout and thus every part is exactly the same.
Hence, it is true.
Reason for wrong statements:
Option d):
A solution is a homogenous mixture and it does not separate into parts. Therefore, the solutes present in a solution will not settle out with time if kept undisturbed.
Hence, the statement is wrong.

True or Falsearrow_forwardYou need to prepare 500 ml PBS buffer, a solution commonly used in biological research. The buffer helps to maintain the pH, and the osmolarity, as well as ion concentrations of PBS buffer, match those of the human body. PBS buffer consists of the following components: 137 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, 1.8 mM KH2PO4. How would you prepare the buffer?arrow_forward
- which of the following is a characteristic of a buffer? a. The pH will go down significantly when H3O+ is added to the buffer b. The pH will go down very slightly when H3O+ is added to the buffer c. The pH will go up significantly when H3O+ is added to the bufferarrow_forwardA researcher prepares 100 mL of aqueous solution containing 0.1 g of a protein. The researcher then uses an experimental apparatus ,where he notes that, at room temperature (300K) and atmospheric pressure (101.325 kPa), distilled water flows naturally into the solution compartment. However, when he applies an extra pressure of 1000 Pa he observes that the flow of distilled water ceases and the system is in balance. Calculate the molar mass of this protein, in kDa (1 Da = 1 g/ mol); Why does the flow of distilled water cease with the application of the pressure of 1000 Pa? Explain in terms of potential chemicals. %3Darrow_forwardThe normal range of the sodium electrolyte in the body is 134 to 145 mEq/L. The term mEq is dependent on the charge of the ion. Since sodium is a +1 ion, 134 mEq/L is the same as 134 mmol/L. An ion that has a greater positive or negative charge; however, will have 1 mEq for each positive or negative charge of the ion for every 1 mmol. For example, for Ca+2, 2mEq/1mmol. If the standard range of Magnesium in the body is 0.70 to 0.95 mmol/L, convert this value into mEq/L for the Mg2+ ion. (Use dimensional analysis to figure this out)arrow_forward
