Write a mechanism (using curved-arrow notation) for the deprotonation of tannins in base. use ar-oh as a generic form of a tannin and use sodium carbonate (na2co3) as the base. balance the chemical equation. comment on the aqueous solubilities of each species (assume that the tannin is insoluble in water initially)

After deprotonation of tannin, tannin (Ar-OH) is converted to salt which is soluble in water and is converted to which is also soluble in water

Explanation:

Sodium carbonate is a strong electrolyte which produces carbonate anion upon dissociation.Carbonate ion is a strong conjugate base of weak acid After deprotonation of tannin, tannin (Ar-OH) is converted to salt which is soluble in water and is converted to which is also soluble in waterBalanced equation: Mechanism has been shown below.

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.
