A well-known basic titration example is the titration of acetic acid (CH3COOH) in vinegar with sodium hydroxide (NaOH): More information of what titration is, can be found at theBasics of Titrationguide. Titration explained: This video shows the basics of titration theory and details the advant...
lower sodium current densities (Fig.4c,d), features all consistent with atrial and pacemaker CMs rather than ventricular CMs. Fig. 4: RA-PSC-CMs are enriched with atrial and pacemaker subpopulations and are highly arrhythmogenic. a, Contribution of cell subtypes from PSC-CMs and RA-PSC-CMs.b...

However, the stability of Potassium peroxymonosulfate is much better under acidic conditions than under neutral conditions, and it rapidly decomposes under alkaline conditions. The compounded Potassium peroxymonosulfate salt is a disinfectant made by combining sodium chloride and organic acids with monopers...
Tetrahydrofuran was distilled immediately before use from sodium-benzophenone ketyl. Methylene chloride, N,N-dimethylformamide, triethylamine, N,N-diisopropylethylamine and chlorotrimethylsilane were distilled from calcium hydride and stored under an argon atmosphere. Methanol was distilled from magnesium and ...
Calcium plays an essential role in physiology of the cardiovascular system. Aberrations from normal serum calcium levels are known to be associated with several cardiovascular diseases. Its possible role as a predictor for long-term mortality after acute myocardial infarction (AMI) is still uncertain....
Reducing sugars react with a color reagent such as 0.05% (w/v) potassium ferricyanide, in 0.5 M sodium bicarbonate. Products of this reaction can be measured by absorbance at 420 nm. The chitinase assay is often affected by the presence of other reducing sugars in the medium,9 however, ...
