Airplane

20
Q

Lewis

A

electrons? Lewis base donates lone pair of electrons
Lewis acid will accept the lone pair of electrons

21
Q

Draw the lewis dot structure for NH3 and H2O

A
22
Q

Describe Titration using words titrant analyte indicator equivalence point and H+ and OH-

A

A process where you add a known amount of a solution or titrant which is of known concentration in order to determine the concentration of a different solution known as an analyte. Drop by drop the indicator is added to the solution until it changes color. The change in color indicates that it has reached its equivalence/endpoint. The point of this process is to get the amount of H+ and OH- to equal amounts so that you can determine the concentration of the unknown substance.
