Â Â Â Â Â Â Â Â Saponification: A. Â Â Â Â Â Â Â Â 1ml of gunk dissolvent + 1 ml of saturated NaCl solution. hither we arrange that in that respect is the white ppt. at the base of the tube. And this kind of ppt. is not soluble in the urine, on the dot soluble in the ether. B. Â Â Â Â Â Â Â Â 1 ml of soap solution + 1 ml of CaCl2 solution. Here we can find there is also the white ppt. at the bottom of the tube. This kind of ppt. is not soluble some(prenominal) in the water and in the ether. C. Â Â Â Â Â Â Â Â 1 ml of soap solution + 1 ml of thin HCl solution. In the test, we found that there be the white ppt.

at the bottom of the tube. This kind of ppt. is also insoluble in the both water and ether. 3.
