Calculate the mass of AgNO3(s) that must be added to 0.500 L of a solution of 0.154 M NaClsolution to precipitate ‘all' of the chloride ion. The ‘all' means that we want to add the same number of moles of silver ion as we have moles of chloride ion present initially. As you know from lab, we call AgCl(s) an insoluble salt.
Solve an equilibrium problem (using an ICE table) to calculate the pH of each solution:a solution that is 0.165M in HC 2 H 3 O 2 and 0.120M in KC 2 H 3 O 2.
A buffer having equal amounts of a weak acid and its conjugate base has a pH =4.4. A small amount of sodium hydroxide was combined to this buffer solution .
What is the ground state electron configuration for the boron atom? What term symbols can arise from this electron configuration?
Why is lip gloss long lasting containing petroleum? How many metric tonnes of 5%-S coal would be required to yield the H2SO4 needed to produce a 2.0-cm rainfall of pH 2.00 over an area of 100 square kilometers?
What do you expect will happen to the position of this equilibrium when the total pressure of the gases in the reaction mixture is doubled by injecting some argon (Ar) while maintaining the temperature constant.
Compute the composition of the crystals and the yield of the process. Also determine the composition of the mother liquor?
