Common-ion effect is a behavior where the ionization of the weal electrolyte is prevented. There are common encountered type of solution that showed this behavior: a weak acid solution plus a soluble ionic salt of the weak acid or base. These are the solutions that are used in the ...
Acidic substances include black coffee, battery acid and lemon juice. Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic. However, the pH level of an acidic solution cannot become greater than 7, because...

Improvements in semen quality resulting from SP supplementation may be attributed to the elevated production of non-enzymatic antioxidants, such as carotenoids, tocopherols, ascorbic acid, and chlorophyll derivatives, as well as enzymatic antioxidants including superoxide dimutase (SOD) and catalase [18,...
on myristic acid (MA) phase change material (PCM) to produce shape-stabilized PCM. The proposal for the use of latex-based elastomeric coating for PCM has been rarely considered in the literature due to a lack of understanding of the crosslink of elastomers. Thus, in this research, the ...
