Solution of compound a and another 1 m solution of compound b and spots both on a tlc plate and runs the tlc. upon visualizing the plate under uv light, the chemist notices that the spot corresponding to "a" is much darker than the spot corresponding to "b". since identical amounts were applied to the plate, how can the chemist explain the differences in spot intensity?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. the values of phosphorous acid are 1.30 6.70 calculate the ph for each of the given points in the titration of 50.0 ml of 1.5 m h3po3(aq) with 1.5 m koh(aq) .

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
