Write net Bronsted equations that show the acidic or basic nature of the following substances, given the pH. For polyprotic acids, only show one proton transfer. Remember that spectator ions are not included.
lithium dihydrogenphosphate with a pH of 4.70
fish (trimethylamine, C3H9N) with a pH of 8.20
milk (lactic acid, HC3H5O3) with a pH of 6.60
tums antacid (calcium carbonate) with a pH of 8.50
nknown gas effuses in 11.0 min. An equal volume of H2 in the same apparatus under the same conditions effuses in 2.56 min. What is the molar mass of the unknown gas
Weigh 3.503g of NaC2H3O2*3H2O and add it into a 150mL beaker. Pour in 8.8 mL of 3M acetic acid. Pour in 55.6 mL of distilled water and add it to the mixture and stir the solution.
