Sorry I cant I just need some points
Carbonic acid (H₂CO₃) dissociation in water takes place in 2 steps. its a polypro tic acid as it has 2 H⁺ ions it can donate.
the dissociation reactions in water are as follows;
H₂CO₃ + H₂O ---> HCO₃⁻ + H₃O⁺
in the first dissociation it releases a proton that combines with water to form a hydronium ion.
HCO₃⁻ + H₂O ----> CO₃²⁻ + H₃O⁺
second dissociation results in the carbonate ion and hydronium ion formation.
As the ratio of acid dissociation constant ka1/ka2 > 10⁴ , dissociation takes place in 2 steps.
Any waves traveling along the medium will reflect back when they reach the end.
In the technique of recrystallization "the mother liquor is the filtrate".
<u>Option: </u>C
<u>Explanation:</u>
The portion of a solution remaining over after crystallization is understood as a mother liquor. It is found in chemical reactions that include sugar refining. It is the liquid produced by filtration of the crystals. The residual liquid, once the crystals have been extracted out as the mother liquor will include a portion of the initial solution as estimated at that temperature by its solubility as well as any unfiltered contaminants. Second and third crystal crops can then be collected from the mother's liquor.
