Answer:
Option b=> 0.1 M CH3COOH , 0.1 M CH3COONa.
Explanation:
In chemistry, when an acid or a base(alkali) is added to a solution and the solution pH does not change then we say that the solution is a BUFFER SOLUTION (that is a solution, upon the addition of acid or base will show resistance in pH value).
In order to be able to answer this question efficiently we have to consider the mathematical representation or Equation below;
pH = pKa + log ( [ A^-] / [HA] )--------------------------------------------------------------------(1).
What the mathematical representation or Equation (1) above is telling is is that if [A^-] or [HA] is high then there will be the production of buffer with higher buffer capacity.
Answer:
10
Explanation:
you can only make 10 ham sandwiches because you only have 30 slices but you could make more without ham
Non-polar Solute and Polar Solvent (and vice versa)
However the molecules in the solute and solvent are only able to make dispersion forces with each other (as they aren't both polar). This only releases very little energy. Therefore overall, more energy is required than released and hence the process won't happen.
