Answer:
Explanation:
From the question we are told that:
pKa for Acetic Acid 
Therefore
For Equal Concentration of acetic acid and acetatic ion
Generally the Henderson's equation for pH value is mathematically given by
Answer:
C). Electronegativity.
Explanation:
'Electronegativity' is described as the tendency or a measure of the ability of an atom or molecule to attract electrons that leads to the formation of chemical bonds. It is denoted by 'χ', a Greek letter. The elements like Fluorine having a very high rate of electronegativity, its atom would attract the electrons more strongly while the elements with lesser electronegativity like Cesium would possess a lesser tendency to attract electrons towards it in order to form a bond. Thus, <u>option C</u> is the correct answer.
Based on concentration of solute particles and hence the osmotic pressure the solutions can be classified into three categories , with respect to other solutions
a) isotonic: when concentration of one of the solution is same as of the other solution then they are referred as isotonic to each other.
b) hypertonic: When concentration of the solution is greater than the concentration of other solution then it is said to be hypertonic.
c) hypotonic: when concentration of the solution is lesser than the concentration of other solution then it is said to be hypotonic.
So a solution with high concentration of solute will have higher osomotic pressure and will called to have high pressure or tone hence called as hypertonic.
Thus compartment A will have high concentration and will called as hypertonic while the compartment B will have low concentration and will called as hypotonic
Explanation:
I think at HF is the answer because the pH value of weak acid are 4 and 5
