OH concentrations were found to be quite elevated for such a dry environment, with average values of 2x106 molecule cm3. Model simulations suggest that much of the observed OH is a result of unexpectedly high NO concentrations. Concentrations of H2SO4 and MSA were generally low with average ...
What is a formula unit?Molecules and Formula UnitWhen elements combine, they form a compound. For covalent compounds, the smallest unit is called a molecule. The counterpart of a molecule in ionic compounds is the formula unit.Answer and Explanation: ...

The pTLC was carried out using 20 × 20 cm RP silica gel glass plates (Merck, Germany) as described by Sherma and Fried31, and the plates were developed using the solvent system MeOH/H2O in a ratio of 8:2. The bands were marked under the UV wavelengths 254 and 365 nm, and t...
A 100-μL aliquot of a solution containing 0.03% H2O2 and 2 mg/mL o-phenylenediamine in 0.1 mol/L citrate buf- fer (pH 5.5) was added. The reaction was terminated by the addition of 50 μL of 2 mol/L H2SO4 as the color changed, and the plate was analyzed using a multi-well ...
In a wet process facility (see figure 1), phosphoric acid is produced byreacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The reaction also forms calcium sulfate (CaSO4), commonly referred to as gypsum. Is citric acid stronger than phosphoric acid?
