Solution : Water and Methanol are easily miscible in any amount. so they are not preferred for the liquid-liquid extraction process.
Liquid-Liquid Extraction is also called as solvent extraction. It is the method of seperation of compound based on their relative solubilities in two different immiscible liquids. Generally we use water (polar) and an organic solvent (non-polar).
It is important that the two solvents should not be mix because it is easy to seperate them.
Water and Methanol are easily miscible in any amount. we can not seperate them easily. So that is why we can not use water and methanol as a solvent in liquid-liquid extraction process.
Explanation:
B. Plant cells is the correct answer
Answer:
1. A. Sour.
B. Irritating
2. A. Slippery
B. Bitter
C. Irritating
Explanation:
Acids induce salivation in the mouth which increases the bicarbonate secretions thus the sour taste. Sour taste receptors detect the hydrogen ion in the acids.
Acids may react with the fluids in the eye and thus irritate the eye cells. This is because they alter the pH of the eye fluids. Once they get into the eye they should be rinsed thoroughly with enough water and professional medical assistance sought.
Bases have a soapy feel in the skin. This is because they dissolve the fatty acids in the skin and form complexes. These complexes have a slippery feel.
The bases taste bitter in the mouth. The OH ions bind to the bitter taste receptors thus causing the bitter taste.
Once these bases get into the eyes, they alter pH of eye fluids thus causing irritation.
Answer:
I'm not really sure if you're interested in the electron dot diagram of the potassium and bromine atoms, or of potassium bromide,
KBr, so I'll show you both. You can use this example to find the electron dot diagram of hydrogen bromide, HBr.
