1. “Salt” (NaCl) is known to be readily soluble in water, however there is a limit to its solubility. The solubility of salt in water at 25° C is 35.9 g/100 mL
a. Explain what the value 35.9 g/100 mL means. .
b. Write this value as two conversion factors.
c. What minimum volume of water would be necessary to dissolve 2.2 kg of salt?
2. A pair of students forgets to precipitate the carbonate ions in their leaf compost jar’s NaOH solution prior to the HCl titration. How would this affect the perceived amount of NaOH present in the titrand?
a. The perceived amount of NaOH would be higher than what it is.
b.The perceived amount of NaOH would be lower than what it is
3.How would forgetting to precipitate the carbonate ions affect the perceived amount of CO2 given off by the leaves?
a.The amount of CO2 would be perceived higher than what it is.
b. The amount of CO2 would be perceived lower than what it is.

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...

2) You are presented with an unknown that possibly has Ag-, Bi-, Sn+, Zn2+, Co2+ and Na'. You divide the solution into three equal volumes, labeling one "A," one "B," and one "C." To "A" you add 6 M HCl and do not observe any precipitate forming. In tube B, you add 6 M HCl until the pH is 0.5 then add thioacetamide and heat the solution in a hot water bath for seven minutes, eventually observing a black precipitate....

g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
