Question

Some splattering of the sample into the watch glass does occur near dryness. In a hurry to complete the analysis, the chemist chooses not to return the splattered solids to the original sample and skips the first part A.3 Will the reported TDS for the water sample be too high or too low? Explain.​

Answer 1

Answer:

• The chemist will consider the total sample for his calculation, however, some sample is not added to the water. Experimental results will correspond to the dissolved sample only, which is less.

• All the dissolved salt of water will not react since the sample added is less than required. So the results of TDS will be low.
