What the Tartrate Does
On their own, copper ions would settle out as copper hydroxide in alkali. The tartrate in solution B holds them in solution as a blue complex, so the copper stays available until a reducing sugar, on heating, turns it into the brick-red copper(I) oxide that marks a positive result.
Handling
The solution is strongly alkaline: wear eye protection and gloves, and rinse splashes off with plenty of water. Keep the cap tight, as the alkali takes up carbon dioxide from the air.
