The correct Answer is:
To solve the question regarding which hormone helps in the maintenance of electrolytes, body fluid volume, and osmotic pressure, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Question**: We need to identify a hormone that plays a crucial role in maintaining electrolytes, body fluid volume, and osmotic pressure. 2. **Analyzing the Options**: The options provided are: - Cortisol - Aldosterone - Oxytocin - Thyroxin 3. **Evaluating Each Hormone**: - **Cortisol**: This is a stress hormone that is released during stressful situations. It does not primarily regulate electrolytes or fluid balance. - **Aldosterone**: This hormone is produced by the adrenal glands and is specifically involved in regulating sodium and potassium levels in the body. It helps in maintaining electrolyte balance, body fluid volume, and osmotic pressure by promoting sodium reabsorption and potassium excretion in the kidneys. - **Oxytocin**: Known as the childbirth hormone, it is primarily involved in labor and lactation, not in fluid or electrolyte balance. - **Thyroxin**: This hormone, produced by the thyroid gland, is mainly involved in regulating metabolism and growth but does not directly influence electrolyte balance or fluid volume. 4. **Identifying the Correct Answer**: Based on the functions of the hormones analyzed, aldosterone is the hormone that directly helps in the maintenance of electrolytes, body fluid volume, and osmotic pressure. 5. **Conclusion**: Therefore, the correct answer to the question is **aldosterone**. ### Final Answer: **Aldosterone** ---

Consider three solutions of 3 strong electrolytes.AB, CD_(2) and EF_(3) The osmotic pressure ratio of I,II, and III is

Solute A is a ternary electrolyte and solute B is non-elctrolyte . If 0.1 M solution of solute B produces an osmotic pressure of 2P ,then 0.05M solution of A at the same temperature will produce on osmotic pressure equal to

The main application of osmotic pressure measurement is in the determination of the molar mass of a substance which is either slightly soluble or has a very high molar mass such as proteins, polymers of various types and colloids.This is due to the fact that even a very small concentraion of the solution produces fairly large magnitude of osomotic pressure.In the laboratory the concentrations usually employed are of the order of 10^(-3) to 10^(-4) M.At concentration of 10^(-3) mol dm^(-3) , the magnitude of osmotic pressure of 300 K is : P=10^(-3)xx0.082xx300=0.0246 atm or 0.0246xx1.01325xx10^5=2492.595 Pa At this concentration, the values of other colligative properties such as boiling point elevation and depression in freezing point are too small to be determined experimentally. Further polymers have following two types of molar masses : (A) Number average molar mass (barM_n) , which is given by (undersetisumN_iM_i)/(undersetisumN_i) where N_i is the number of molecules having molar mass M_i . (B) Molar average molar mass (barM_m) , which is given by (undersetisumN_iM_i^2)/(undersetisumN_iM_i) Obviously the former is independent of the individual characteristics of the molecules and gives equal weightage to large and small molecules in the polymer sample.On the other hand later gives more weightage to the heavier molecules.Infact with the help of a colligative property only one type of molar mass of the polymer can be determined. One gram each of polymer A (molar mass=2000) and B(molar mass=6000) is dissolved in water to form one litre solution at 27^@C .The osmotic pressure of this solution will be :
