Problem- Enough of a monoprotic acid is dissolved in water to produce a 0.0121 M solution. The pH of the resulting solution is 2.38. Calculate the Ka for the acid
Write complete steps
What is the maximal amount of lead (II) iodide (the theretical yield) that can be obtained when 0.75 moles of lead (II) nitrate and 83 g potassium iodide are mixed together
My paper says that will be only one isomer out of hexabromobiphenyl, C12H4Br6 And it states also that one phenyl group is still the active substituent when it is bromized. I wonder why it is only one isomer and I will be so thankful if you can dra..
A given PH meter can be read with a standard deviation of +- PH units throughout the range 2 to 12 calculate the standard deviation of [H3O+] at each end of this range
what is the depth below the surface at which the concentration is 1016 atoms/cm3 if the surface concentration is maintained at 1018 atoms/cm3? Use D = 2 x 10-12 cm2/s for aluminum diffusing in silicon at 1100?C.
