When an ionic compound such as sodium chloride (nacl) is placed in water, the component atoms of the nacl crystal dissociate into individual sodium ions (na+) and chloride ions ( in contrast, the atoms of covalently bonded molecules (e. g., glucose, sucrose, glycerol) do not generally dissociate when placed in aqueous solution. which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions)? a) 1 l of 1.0 m nacl b) 1 l of 0.5 m nacl c) 1 l of 0.5 m glucose d) 1 l of 1.0 m glucose e) c and d will contain equal numbers of particles.

Answer asap need 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.
