Can you help me with number 28
27 28 29 30 Which of the following buffer solutions will best protect around a pH of 11.0? Assume all chemicals are 1.0M in solution What is the final pH when a solution is made that contains 0.250M HNO₂ and 0.450M KNO₂2 Ka HNO₂ = 7.2*10-4 W What is the final pH when a buffer contains 1.00 mol of CH3NH2 and 2.00 mol of CH3NHst. 0.750 mol of NaOH is added to the solution. Assuming no dilution, what is the final pH of the solution? CH3NH2 Kb = 4.3*10-4 .100 moles of HCI is added to a 1L mixture of 100M HC3HsO2 and 0.180M KC3H5O2. Assuming no volume change, what will be the final pH in the solution? Ka HC3H5O2 4.5*10-5 > Tim Il Proctoric
