Section Name Experiment 2 Advance Study Assignment: Properties of Systems in Chemical Equilibrium 1. Methyl orange, HMO, is a common acid-base indicator. In solution it ionizes according to the equation: HMO(aq) H(aq) + MO (aq) red yellow If methyl orange is added to distilled water, the solution turns yellow. If a drop or two of 6 M HCl is added to the yellow solution, it turns red. If to that solution one adds a few drops of 6 M NaOH...

How does Physical Weathering change the chemical composition of a rock material? It creates new, different minerals from the old minerals It doesn't change the chemical composition of a rock material It dissolves soluble minerals, moving ions into solutions It relies on chemical reactions to break down the minerals In the ASCE or USBR Rock Weathering Descriptors, the description of "Moderately Severe" says that all (minerals) except quartz are discolored or stained, and that all feldspars are dull, discolored and...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
