Sodium Bicarbonate is the monosodium salt of carbonic acid with alkalinizing and electrolyte replacement properties. Upon dissociation, sodium bicarbonate forms sodium and bicarbonate ions. Ion formation increases plasma bicarbonate and buffers excess hydrogen ion concentration, resulting in raised blood pH.

Most phenols are weak acids (pK a = ~10) and do not react with sodium bicarbonate, which is a weak base itself (pK a (H 2 CO 3)=6.37, 10.3).However, they do react with a strong base like NaOH. This difference in acidity can be exploited to separate carboxylic acids and phenols from each other in an organic layer.

Why did you wash the crude cyclohexene with saturated sodium bicarbonate? Sodium bicarbonate is a base and since there is a lot of catalytic acid being formed in the reaction, the base will neutralize the acid that is leftover after distillation. Since cyclohexene is insoluble in water, sodium bicarbonate was a good choice as none of the ...

Sodium bicarbonate (NaHCO 3), also called baking soda, is a white, crystalline powder that is commonly used as a pH buffering agent, an electrolyte replenisher, systemic alkalizer and in topical cleansing solutions.Sodium bicarbonate is a salt that breaks down to form sodium and bicarbonate in water. This breakdown makes a solution alkaline, meaning it is able to …

Sodium hydroxide is usually easier to handle because it does not evolve carbon dioxide as a byproduct. In addition, the concentration can be increased significantly if is needed. However, if compounds were present that are sensitive towards strong bases or nucleophiles (i.e., esters, ketones, aldehydes, etc.), sodium bicarbonate should be used.
