What is the pH of pure water at 40 degrees C if the Kw at this temperature is 2.92 x 10 to the -14th?
What volume of 1.40M NaOH solution must you add in order to prepare an acetate buffer of pH = 4.83? (The pKa of acetic acid is 4.76).
calculate the mass of agcl and h2s formed when 85.6 g of ag2s reacts with excess hcl.
Gas Nitrous Oxide (N20) is used as an anesthetic and in aerosol cans to produce whipping cream. It is a potent greenhouse gas and decomposes slowly to N2 and O2.
