3M Sodium Chloride
Add 17.5g of NaCl to 100 mL volumetric flask
and fill to the mark with distilled water. This
electrolyte can be used where potassium and
ammonium ions cause interference.
1M Lithium Chloride
Add 4.24g LiCl to a 100ml volumetric flask and
fill to the mark with distilled water. This
electrolyte
is used in non-aqueous
measurements and titrations. In less polar
solvents, making up the LiCl in ethanol or
isopropanol may give better results.
