Negative deviation occurs when the total vapour pressure is less than what it should be according to raoult's law. considering the same a and b components to form a non-ideal solution, it will show negative deviation from raoult's law only when: o a. pia p[ao] times x[a] and p[bi < pibo] x[bi as the total vapour pressure (p[ao] xia] + p[b0] xib]) is less than what it should be with respect to raoult's law. o b. the solute-solvent interaction is stronger than solute-solute and solvent-solvent interaction o c. the enthalpy of mixing is negative because stronger attractions are formed. o d. the volume of mixing is negative becasue stronger attractions have led to a contraction in volume o a and b only o a, b and c only all of the above

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
