Calculate the molar solubility of Fe(OH)2 when buffered at pH of 7.2
sample of an unknown monoprotic acid was titrated with 0.105. Determine the molar mass of the acidMKOH
Calculate the pH of 15 mL of water after 0.15 mL of 1M HCl is added. Assume that the total volume of the solution remains 15 mL.
Buffers are typically made by combining a weak acid with its salt or by combining a weak base with its salt. Which of the following will be the other component present in a prepared buffer if one component was NH4Cl?
d. none of the above
you wish to prepare HC2H3O2 buffer with a pH of 5.44. If the pKb og C2H3O2 is 8.56, what ratio of C2H3O2/HC2H3O2 must you see? explain!options:0.700.201.45.01.1
I dont fully get the way that a buffer solution should be expressed from start to finish. could someone explain the dynamics of it to me?
