A) What is the PH of a buffer prepared by adding 0.708 mol of weak acid HA to 0.507 mol of NaA in 2.00 L of solution? The dissociation constant Ka of HA is 5.66*10^-7?
B) What is the PH after 0.150 mol of HCl is added to the buffer in part A? Assume no volume change on the addition of acid?
c) What is the PH after 0.195mol of NaOH is added to the buffer in part A? Assume no volume change
Imagine that the gas shown in the simulation is an ideal gas such as helium. Notice that the final number of moles of gas is 1.00 mol for each experimental run.
Potassium nitrate decomposes on heating, producing potassium oxide and gaseous nitrogen and oxygen: 4KNO3(s)→ 2K2O(s) + 2N2(g) + 5O2(g)
Why does the integral heat of solution at infinite dilution equal the differential heat of solution at zero molality. Why would the slope of a plot of the integral heat of solution versus molality approach zero as the molality approaches zero
