Explanation:
Water filtration is the process of removing or reducing the concentration of particulate matter, including suspended particles, parasites, bacteria, algae, viruses, and fungi, as well as other undesirable chemical and biological contaminants from contaminated water to produce safe and clean water for a specific purpose ...
The molarity is the number of moles of solute dissolved in one liter of solvent. It is calculated using the formula M = n/V. To find the volume we have to specify the number of moles dissolved to get the required molarity concentration which is 0.200 m.
Calcium hydroxide may be used in the process of titration with acids to get a neutral solution and determine the unknown concentration of the acid. In such case we use the following formula;
M1V1 = M2V2
M1 is the molarity of CaOH
V1 is the volume of CaOH
M2 is the molarity of the acid
V2 is the volume of the acid
In order for sound to be hear, it must travel through a medium, such as air, through which its waves can make a disturbance. In space there is no air, so microphones must be used.
