with 7 being neutral. pH actually stands for "power of hydrogen" and the scale is a measurement of the concentration of hydrogen ions (H+) in a solution. Acidic solutions have a higher concentration of hydrogen ions than water, and basic solutions have a lower concentration of hydrogen ions...
A polymer that is not one of the types listed in Schedule 7 and that has an average molecular weight greater than 1 000 daltons and equal to or less than 10 000 daltons, with less than 10% of its components having a molecular weight of less than 500 daltons and less than 25% of its...
the lanthanide ion before the detection is dissociated from the active substance for instance by adding a buffer with a pH value below 3.5 and a splitting detergent, whereafter the excitation in the determination takes place in the solution in the presence of a &bgr;-diketone by using a short...

0.5 g compound 1 was added with portion to a stirred mixture of 98% H2SO4 (10 mL) and fuming HNO3(10 mL), while maintaining the reaction temperature below 0 °C. After the addition was complete, the ice bath was removed, and the mixture was allowed to warm slowly to 50...
Figure 1. The atmospheric boundary layer is coupled to the oceanic boundary layer and the wave layer with wave-dependent roughness from above, z0a, and roughness from below, z0s. Air–sea fluxes have traditionally been estimated by a using bulk transfer coefficient (for momentum it is called ...
By virtue of the fact that the process according to the invention can be carried out at ambient temperature or even at a temperature below ambient temperature, it can be used with particular advantage for separating one or more substances of low molecular weight from a liquid medium additionally...
A 300-mL flask with a stirrer, a thermometer, a reflux condenser, a nitrogen gas introduction tube, and a dropping funnel was charged with 15 g of maleic anhydride, 69.2 g of methyl t-butyl ether (MTBE), and 0.3 g (1.0 wt % relative to the copolymer produced) of polyisobutylvinylethe...
