Carefully in a fume hood add the 41 ml of con HCl then fill the remainder of the volumetric flask to the mark at 1 Liter. Shake it thoroughly and be sure to label it! 1 Leliz Lampe Follow You will need some concentrated HCl, say 6 molar. The question becomes: How many mL of ...
When determining the volume of the flask, the student did not fill the flask completely with water and left approximately 1 mL of air at the top of the flask prior to weighting it. What will be the effect on the measured density of the ...
How would you prepare 100 mL of a 155 ppm solution of urea in water? How much of a 0.35 M solution of Fe2+ is needed to make a solution of 1.5 mM Fe2+ in a 100 mL volumetric flask? A solution is labeled 100 ppm MgCl2. What...
Position of eye at all volumetric vessels must be at the same level as the meniscus to avoid a parallax error. Why is graduated cylinder more accurate? The accuracy of a graduated cylinder is higher because the graduations on the cylinder make it easier to more precisely fill, pour, measure...
9.0gm of AgNO3 solution is put into a 500mL flask. Fill up the remainder of the flask with distilled water. So the moles in this solution are 1.0 M. This solution is a standard against the sodium chloride solution (NaCl). Experimental Work – Steps: Take 50mL of sodium...
A test liquid has a density of 1.1 g/mL. When you pour some of it into a cup of water, what will happen? When determining the volume of the flask, the student did not fill the flask completely with water and left approximately 1 mL of air at...
The ratio of the compacted fill to the apparent density indicates the proportion of the fill made of activated carbon. The rest forms the empty space between the activated carbon particles and thus the porosity or the interstitial volume. 5. Characterization of Chemical Properties of Activated Carbo...
