Filter paper

Your air conditioner's air filter may seem like a minor component, but in actuality, the filter is extremely crucial to your system's overall operation. A dirty air filter can negatively affect your air conditioner in a variety of ways. To help you better understand the importance of changing your unit's filter, we've created a list of problems a dirty filter can cause. How does an air filter work? Before we discuss the affects of a dirty air filter, lets talk about how a clean filter works. A filter's most basic function is to stop contaminants from traveling through your unit and into your home. Particles, such as dust, mold spores, animal fur, and bacteria are trapped and held by the filter. Eventually the air filter will become too…

When both solutions are mixed a white precipitate (Calcium Carbonate) is formed alongside Sodium Chloride. A clear colourless liquid is observed as the white precipitate is filtered through the filter paper.…

sulfate and tare weight of the beaker – Mass of 100 mL beaker = Mass of copper sulfate 53.84g – 50.89g = 2.95g The mass of the copper sulfate is 2.95g. 3. Mass of starch and tare weight of filter paper – Mass of the filter paper = Mass of starch 3.46g – 0.50g = 2.96g The mass of the starch is 2.96g. 4. Mass of water / Mass of Mixture #6 x 100% = Percent of water 32.68g / 38.59g x 100% = 84.68% The percent of water in the mixture is 84.68%. 5. Mass of copper sulfate / Mass of Mixture #6 x…

residue on the filter paper is the solid (we may or may not want to keep depending on the experiment). Evaporation is the separation of a liquid and a soluble liquid. In evaporation the solution is heated to the boiling point for the liquid to evaporate.…

purified compound, therefore there are many factors that affected the crystallization . One of the factors affecting our product was adding too much solvent at at time. Since too much solvent was added, p-hydroxybenzoic pure acid stayed dissolved in the solution, eventually the percentage recovered was lower than it should be. A high percentage yield is considered between 70-80% of the purified product, in order to obtain this results we need to use little solvent as possible. On the other…

Percentage Yield of a Chemical Reaction Question: What is the percentage yield of the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride…

side of a 400-mL beaker. Experimenters cleaned the stem with a moistened pipe cleaner. They prepared a piece of quantitative filter paper, folded it in half leaving about 1 mm difference between the two long edges, fold it in half again leaving the same difference between the two edges, and tore off part of the paper that corresponded to being a small portion at one corner of the paper when it was only folded in half. Then they opened the paper, forming a cone so that three layers of the paper…

will form. As evident from using gravimetric analysis in the second task, choosing a compound with low insolubility proves very difficult to filter and separate from the filtrate, therefore, resulting in needing to filter the precipitate more than once and still ending up with a low percentage yield and high error calculation. However, the contamination of a precipitate does not significantly alter the results for colourimetic analysis, as evident from the absorbance and concentration calculated…

The purpose of this experiment was to calculate the percent yield of copper after conducting series of chemical reactions. To study the % yield of copper in the copper cycle, the initial mass and final mass of copper was measured. The chemical reactions involved in the copper cycle are dissolution, precipitation, dehydration, and oxidation/reduction. First, copper was reacted with in a beaker to form (aq) and . The purpose of the dissolution reaction is to convert the copper into solutes in…

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…
