Suppose you mistakenly used tap water instead of distilled water to dissolve your consumer product. When you did the test for chloride, you observe formation of a white precipitate after addition of silver nitrate. Can you rightly conclude that the product being tested contains chloride? Explain your reasoning.

The graphic below shows the general procedure for titrating the saturated solution of magnesium hydroxide with hydrochloric acid. Select all of the true statements from the choices below. 1. Obtain a saturated solution of magnesium hydroxide. 0 2. Transfer 30.0 mL to an Erlenmeyer flask using a volumetric pipet. Add phenolphthalein. 3. Titrate to a colorless endpoint using 0.0020 M hydrochloric acid. It is important that the aliquot drawn in step 2 does not contain undissolved magnesium hydroxide solid. For titrations of the saturated solutions at elevated temperatures, the solution must be held at high temperature for the duration of the titration. Hydrochloric acid is the analyte in this titration. The volume of liquid in the buret should be read before and after the titration. At the endpoint of the titration, the solution will turn from colorless to pink.

A 0.735 g sample of wheat flour was analyzed by the Kjeldahl method. The ammonia formed by addition of concentrated base after digestion with H2SO4 was distilled into 50 mL of 0.10 M HCl. The excess HCl was then back titrated with 22.3 mL of 0.15 M NaOH. Calculate the percent protein in the wheat flour sample (6.25 g of cereal protein for every g of N).
A 1.43 x 10-4 L solution of 45.7 mg/mL protein was analyzed using the Kjeldahl procedure. After digestion of the protein, the liberated NH3 was collected in 9.80 mL of 0235 M HCl. The unreacted acid required 10.75 mL of a standard solution of 0.0149 M NaOH for complete titration. Calculate the weight percent of nitrogen in the protein. (Molar mass N = 14.00674 g/mol)
why does this happen? After the sodium oxalate was added to the lead nitrate, a white precipitate formed immediately. After letting this solution sit for a few minutes, the precipitate fell to the bottom of the test tube. There was about 2.4 cm of white precipitate at the bottom of the test tube. After the nitric acid was added, there was only 0.3 cm of precipitate at the bottom of the test tube.
Which of the following is completely true regarding the titration of iron oxalate salt with EDTA? It was a redox titration, and the color changed from purple to yellow due to the disappearance of the purple reactant. It was a chelometric titration, and the color changed from purple to yellow, due to the disappearance of the purple reactant. It was a redox titration, and the color changed from yellow to pink due to the indicator added. It was a redox titration, and the color changed from yellow to pink due to the color of EDTA. It was a chelometric titration, and the color changed from clear to pink, due to the indicator added. A Moving to another question will save this response. «> MacBook Air F10 F9 F8 F7 000 D00 F4 F6 F5
