Explanation / Answer
Answers:
1. in humans what is the most important solvent?
A: Water is the most important solvent in any living organism. Hence known as the universal solvent.In humans, it constitutes about 50-75% of weight and is the location where all the biochemical reaction takes place in the body.
2. list the two things in humans that might be a solute?
A: Solutes are substances that can be dissolved in solvents to give a homogeneous solution. The human body has two important fluid compartments, the ECF and the ICF which carries many solutes dissolved in it examples are Na+ ion, chloride ions in the plasma, protons in the cytosol, potassium and phosphate in the ICF.
3. Name a solution in humans?
A: The most important solution in the human body is the blood. It has all the electrolytes like sodium ions, bicarbonate ions, chloride ions, glucose, urea etc dissolved in it.
4. Name a colloid in humans?
A: Blood is also a colloid in the human body due to the presence of plasma proteins, globulins etc in it.
5. Name a suspension in humans
A: A suspension is formed when the substances in are distinguishable and observable and can be separated from, ; heterogenous in nature but do not react chemically with one another e.g The RBC's are suspended in the plasma
6. List where an emulsion might occur in humans?
A: Liquids in liquids; fats for their absorption needs to be emulsified into small droplets and then digested and absorbed into blood and tissues.
7. What is the normal ph range of human blood?
A: 7.35-7.45.
8. Where in humans is the ph range likely to be the highest?
A: The pH is highest in the bile when it just formed before the storage in the gallbladder. It is in a range of 8-8.6 reduces to 7-7.6 when stored in the gallbladder and is received first by the duodenum.
9. Where in humans is ph likely to be the lowest?
A: The stomach has the lowest pH of 0.9-1.2, since it secretes hydrochloric acid.
10. What happens to blood ph when you hold your breath?
A: When we hold our breath, CO2 gets accumulated within the blood causing the blood pH to fall and become slightly acidic.
11. What ph would have 10,000 times fewer H+ than a ph of 6?
A: 10000 times fewer H+ means, the referred pH is alkaline in nature or the pH is high. So, the ph here is 10.
