Think of different instances from everyday life that involve one or more substances (solutes) dissolving in water. What can your observations tell you about the type of solution formed? Is it a strong electrolyte, weak electrolyte, or nonelectrolyte solution?  How do the properties of the solution differ from that of a pure solvent? Include a list of references.

Will the calculated Molarity of NaOH be too high or too low or unaffected if the following happen: When you answer the question, consider how the situation affects the calculation of molarity of NaOH and moles NaOH, which is calculated from the mass of KHP. For each answer, you must supply a clear explanation for your answer. Often times, students will restate the facts rather than explaining why they chose the answer they chose. a) You add the weighed KHP to a flask containing a 60mL of water rather than 50 mL of water. Explain. Your answer must contain a well-thought-out and clearly written explanation. b) The buret is still wet with water on the inside when you add your NaOH solution. Explain c) The KHP is wet when you weigh it. Explain. d) You titrate past the equivalence point by 0.50mL Answer a-d

Your lab partner gets out a 100-mL graduated cylinder and a 100-mL beaker to prepare 100.00 mL of 0.1201 M solution from a 1.201 M solution by dilution. What are the two correct pieces of glassware that should be used? Explain.

Glucose (molar mass=180.16 g/mol) is a simple, soluble sugar. Glucose solutions are used to treat patients with low blood sugar. Suppose you prepare a glucose solution using the described procedure. • Step 1: Dissolve 240.6 g of glucose in enough water to make 500.0 mL of solution. • Step 2: Transfer 18.6 mL of the solution to a new flask and add enough water to make 250.0 mL of dilute solution. What is the concentration (in M) of the glucose solution at the end of the procedure?

A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.0740 L sample, the chemist measures 562 µg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: concentration: ppm ppb

at a certain temperature,1.85 grams of barium hydroxide will dissolve to form 100.0 ml of a saturated barium hydroxide solution. the molar mass barium hydroxide is 171.34 grams/mole. what is the concentration of the solution in unit molarity? what is the constitution of the hydroxide ion in the same solution?

What do you understand about the manufacture of chemical solutions? How to (a) make 1000 mL of 0.2 N hydrochloric acid solution from 1 N standard solution and (b) make 100 mL of 0.5 N sodium hydroxide secondary standard solution (known BM = 40 g / mL)? Explain!

When using volumetric flask, why do we have fill it exactly on the given mark? What would be the effect of adding liquid beyond the calibration mark on a volumetric flask? If this happens in the course of preparing a volumetric solution, what should be done?

Most biological reactions take place in an aqueous (water-filled) environment. For example, salts like NaCl readily dissolve in water. However, NaCl is not soluble in a solvent like benzene. Based on what you know about the chemistry of water, explain why this is the case.

Imagine a small amount of each compound in the table below is dissolved in water. Pick the sketch that best shows what the solution would look like, at the atomic level. The large number of faint red and white molecules in the background of each sketch represent the water solvent. Also, the colors of the solute atoms may not mean the same element in each sketch. For example, solute oxygen atoms could be colored yellow in the first sketch but blue in the second. Chlorine atoms could be colored blue in the first sketch but yellow in the second. And so on. Note for advanced students: the sizes of the atoms and any bond angles may not be accurate.
