why is it necessary to test the ph? EXTRME DETAIL PLEASE PROCEDURE To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2 mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL) was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture was gently stirred to ensure complete mixing. Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentle stirring. The pH of the resulting reaction mixture was determined and adjusted to >10 by dropwise addition of 10% sodium hydroxide.

PROCEDURE
To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2
mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)
was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture was
gently stirred to ensure complete mixing.
Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentle
stirring. The pH of the resulting reaction mixture was determined and adjusted to >10
by dropwise addition of 10% sodium hydroxide.
