1. A liquid chemical container apparatus for dispensing liquid chemical, the apparatus allowing measurement of both concentration and amount of a liquid chemical in the liquid chemical container, the apparatus comprising: (a) a container body having an optical member optically connected to said container body, the optical member having a distal end and a proximal end, the distal end adapted to extend into the liquid chemical contained in the container body; (b) a light source optically connected to said optical member, said light source able to transmit light through the optical member; (c) a light receptor optically connected to said optical member, said light receptor able to receive light reflected from said liquid chemical, said light reflected from said liquid chemical being transmitted through said optical member; and (d) means for optical discrimination between liquid chemical of different optical properties, said means for optical discrimination optically connected to said optical member. 2. The apparatus of claim 1 wherein said optical member is an optical fiber transmission/reflection probe. 3. The apparatus of claim 1 wherein said means for optical discrimination is selected from a group consisting of human vision and machine vision. 4. The apparatus of claim 3 wherein said machine vision is a spectrometer. 5. An apparatus for dispensing liquid chemical, the apparatus allowing measurement of both concentration and amount of a liquid chemical in the liquid chemical container, the apparatus comprising: (a) a container body having a plurality of optical members connected to said container body, said plurality of optical members allowing optical access to liquid chemical contained within said container body, the plurality of optical members positioned on said container body in a fashion so that a user may determine the presence or absence of said liquid chemical at the points where each of said plurality of optical members is positioned; and (b) means for optical discrimination between liquid chemical of different optical properties, said means for optical discrimination connected to at least one of said plurality of optical members. 6. The apparatus of claim 5 wherein said means for optical discrimination is selected from a group consisting of human vision and machine vision. 7. The apparatus of claim 6 wherein said machine vision is a spectrometer. 8. A liquid chemical container apparatus for dispensing liquid chemical, the apparatus allowing measurement of both concentration and amount of a liquid chemical in the liquid chemical container, the apparatus comprising: (a) an optical member optically connected to said container body, the optical member having a distal end and a proximal end, the distal end adapted to extend into the container body but not touching liquid chemical contained in the container body; (b) a light source optically connected to said optical member, said light source able to transmit light through the optical member; (c) a light receptor optically connected to said optical member, said light receptor able to receive light reflected from said liquid chemical, said light reflected from said liquid chemical being transmitted through said optical member; and (d) means for optical discrimination between liquid chemical of different properties, said means for optical discrimination optically connected to said optical member. 9. Apparatus in accordance with claim 8 wherein said means for optical discrimination is selected from a croup consisting of human vision and machine vision. 10. The apparatus of claim 9 wherein said machine vision is a spectrometer.
