A- Calculate the concentration of a phosphoric acid solution if 42.0 mL of H3PO4(aq) requires 0.513 mol of NaOH(aq), for complete neutralization.
A- Calculate the concentration of a phosphoric acid solution if 42.0 mL of H3PO4(aq) requires 0.513 mol of NaOH(aq), for complete neutralization. H3PO4 +3NaOH --> Na3PO4 + 3H2O
B- How many moles of aluminium are required to react with 459 mL of 2.1 mol/L hydrochloric acid?
C- What volume, in mL, of 4.1 mol/L sulfuric acid is required to completely react with 30.5 mL of a 4.25 mol/L ammonia solution? H2SO4 +2NH3 --> (NH4)2 SO4 / D- After a rainstorm, the pH of water in a river is slightly lower because rainwater contains dissolved carbonic acid. The concentration of hydronium ions (H3O) in the rainwater is less than the concentration of carbonic acid (H2CO3) in the rainwater because H2CO3 is / a- strong acid and does not completely ionize / b- weak acid and does not completely ionize / c- strong acid and completely ionizes/ d- weak acid and completely ionizes
