A balloon is inflated with 0.2494g of helium to a pressure of 1.26 atm. If the desired volume of the balloon is 1.25L, what must the temperature be in degreeC?
How would you prepare a liter of "carbonate buffer" at a pH of 10.10? You are provided with carbonic acid (H2CO3), sodium hydrogen carbonate (NaHCO3), and sodium carbonate (Na2CO3). Ka value of H2CO3= 4.2x10^-7
After the addition of the water, the volume is now 480 mL. To this solution, we add 20.0 mL of 5 molar NaOH. What is the pH of the buffer now. What would be the pH after an addition of 60.0 ml of the 5.00 molar NaOH was added to the solution formed..
