Suppose the water sample has a relatively high percent of volatile solid material. How would this have affected the reported mass of:
a. dissolved solids -- too high, too low, or unaffected? Explain.
TDS will be unaffected
b. total solids -- too high, too low, or unaffected? Explain.
TS will be too high because of the presence of the volatile solid
c. suspended solids -- too high, too low, or unaffected? Explain.
TSS will be unaffected
i really don't know if I'm right, and i don't know how to explain. Please help!
To determine the impact of high volatile solid material on the reported mass of different solids in a water sample, let's break down each case:
a. Dissolved solids (TDS): The presence of volatile solid materials in water will not affect the measurement of TDS. This is because TDS refers to the total amount of all inorganic and organic substances dissolved in water, including volatile compounds. Therefore, when measuring TDS, both volatile and non-volatile substances are accounted for. As a result, the reported mass of dissolved solids will be unaffected.
b. Total solids (TS): TS measures the total amount of both dissolved and suspended solids in water, including both volatile and non-volatile compounds. In this case, the presence of volatile solid material will increase the reported mass of total solids. This is because volatile solids are included in the measurement of TS, and their contribution will add to the overall mass of solids.
c. Suspended solids (TSS): TSS refers specifically to solid particles that are suspended in water and can be retained by a filter. As volatile solid material is not a suspended particle, it will not have any effect on the measurement of TSS. Therefore, the reported mass of suspended solids will be unaffected.
In summary:
a. Dissolved solids (TDS) will be unaffected.
b. Total solids (TS) will be too high.
c. Suspended solids (TSS) will be unaffected.
To explain these answers, you can use the definitions and principles behind the different measurements of solids in water. Emphasize that TDS includes both volatile and non-volatile dissolved substances, while TS accounts for all solids, including volatile material. Finally, highlight that TSS only refers to suspended solid particles and does not include volatile compounds.
