A chemist must prepare 500.0mL of hydrochloric acid solution with a pH of 0.50 at 25°C .
He will do this in three steps:
Fill a 500.0mL volumetric flask about halfway with distilled water. Measure out a small volume of concentrated ( 8.0M ) stock hydrochloric acid solution and add it to the flask. Fill the flask to the mark with distilled water.
Calculate the volume of concentrated hydrochloric acid that the chemist must measure out in the second step. Round your answer to
Ch4 and ph3 are both covalent since they are composed both of non-metals. ch4 is non- polar because of london forces and has a geometry of tetrahedral ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
