Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

A drinking water treatment plant wants to compare the efficacy of three different solid coagulants, Alum [Al(OH)3(s)], Lime (CaCO3(s)), and Ferric Chloride (FeCl3(s)), for removing the phosphate (PO43-) level to 1 mg/L. The following are the equilibrium reactions [and the respective equilibrium constants (or solubility products, Ksp)] that result in phosphate removalfor each solid, the second reaction being more relevant in each case: Alum: Al(OH)3(s) ↔ Al3+ + 3OH- AlPO4(s) ↔ Al3+ + PO43- Ksp = 9.84 x 10-21 Lime: CaCO3(s) ↔ Ca2+ + CO32- Ca3(PO4)2(s) ↔ Ca2+ + PO43- Ksp = 1 x10-27 Ferric Chloride: FeCl3 (s) ↔ Fe3+ + 3Cl- Fe(PO4)(s) ↔ Fe3+ + PO43- Ksp = 1x10-26.4 What concentrations of Fe 3+, Al3+, and Ca2+ will be needed to maintain a phosphate concentration of 1 mg/L?

We propose an experimental activity that will allow you to do something similar to what is done in the salt flats. Suppose you have a mixture of salt and chalk and you want to separate its phases. Can you think of how to do it? Materials: pieces of chalk, coarse or fine salt, water, a transparent heat-resistant container, a spoon, a heat source (lighter or heater).Solution: Mix equal amounts of salt and chalk in the container. In this way, you will have obtained the heterogeneous system with which you are going to work. Add water and stir with the spoon. Let stand.a) What happened?b) How do you explain what you observed?Two processes have occurred:the dissolution of the salt and the sedimentation of the chalk.Both the chalk and the salt are still present, only the salt is not visible because it is dissolved in the water. The identity of each of the materials was not affected: we say that physical changes have occurred in the system. The materials that constituted the initial…
