At 20 Celsius, a saturated solution of NaCl in water has a concentration of 380 g of sodium chloride per liter of solution. How many g of NaCl are required to make 4 L of the saturated solution? Which is the solute and which is the solvent in this example.
The concentration of the HCl solution is 0.1016 M HCl. What volume of 0.1338 M Ba(OH)2 would neutralize 50.00 mL of the HCl solution standardized in the situation above.
An aqueous solution containing 5.0 g of solute in 100 ml is extracted w/three 25 ml portion of diethyl ether. What is the total amount of solute
what products may have been formed during the combustion of the gas?
Use the graph from the Introduction that plots the density of ethanol solutions from 20 to 60 mass percent to answer the following questions:
a sample of KHC2O4 weighing 0.717g was dissolved in water and titrated with 23.47 mL of an NaOH solution. caluculate the molarity of the NaOH solution.
Solubility of calcite (CaCO3) will increase with a decrease in temperature and decrease with an increase in temperature. This is because the solubility of calcite is dependent on the solubility of CO2.
Limestone (CaCO3) is used to remove acidic pollutants from smokestack flue gases. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite
0.3 M NaH2PO4 calculate acidic and basic buffer capacity. How muc of strong base needed to bring buffer pH one unit up?
Write the two chemical equations that show the titration reactions of the carboxylic acid group and the amino group of glyclyglycine
Evaluate the operating conditions of the chiller - what temperature must the chiller operate if the product streams are also at 1 atm total pressure?
Three Introductory Chemistry students each measured 50.0 mL of 1.0 M NaOH into "double-walled" styrofoam cup calorimeters. Then, Sue added 50.0 mL of 1.1 M HCl to her NaOH solution
As you may well know, placing metal objects inside a microwave oven can generate sparks. Two of your friends are arguing over the cause of the sparking, with one stating that the microwaves "herd" electrons into "pointy" areas of the metal object,
