Based on the Lewis theory of acids and bases, any species that can accept a pair of electrons can act as an acid and any species that can donate a pair of electrons can act as a base. We should expect that many solutions contain species that fall into one of these categories or both...
If the substance is an element, ion, acid, base, or ionic compound, it will determine "n". How is equivalent weight calculated? Equivalent Weight is calculated by taking the molar mass divided by n number of equivalents. The molar mass is the molecular weight. The n number of equivalents...
However, carbonic acid is unstable and often dissociates into a proton (which is donated to a base) and bicarbonate, which has a charge of -1. Loss of the other proton yields carbonate, which has a charge of -2.Carbonic acid is often described as a respiratory acid since it is the ...
How is an acid different from a base?Acidic solutions and Basic solutions:A solution is said to be acidic if it possesses more hydrogen ion concentration. A solution is said to be basic if it possesses more hydroxide ion concentration. The pH of acidic solutions possesses a value smaller ...
Lewis Structures: Lewis structures are pictoral diagrams of molecules used to demonstrate the arrangement of covalent bonds between atoms. They are determined by trying to satisfy the octet of each atom whilst ensuring that the total number of valence electrons in the molecule overall stays constant...
During this time, the winemaker samples the fermenting must and measures the pH or acid levels and sugar content to determine that the fermentation process is proceeding as it should. To make a dry wine, the winemaker will allow the yeast to transform all of the sugar into alcohol. When ...
Topoisomerases are involved in a range of cellular nucleic acid transactions, including DNA replication, transcription, packaging, compaction, recombination and repair. Topoisomerases interact with various proteins in the cell to accomplish these tasks. Post-translational modification of eukaryotic topoisomeras...
platelet donation characteristics on outcomes, and to determine the optimal thresholds for platelet transfusion before invasive procedures or major surgery (eg, laparotomy). Platelet transfusion policies should move toward a risk-adapted approach that does not focus solely on platelet count. ...
who had worked with Macklemore and Lewis on their track "White Walls." It was a big opportunity for Lambert, as Macklemore & Ryan Lewis were coming off of a No. 1 hit with 2011's "Can't Hold Us." But more importantly, she was a...
Randall E Lewis View bio Steps for How to Calculate pH of Salt Solutions Step 1: Read through the given information, and determine if the salt comes from a weak acid or weak base. Step 2: Write the hydrolysis reaction that comes to equilibrium Step 3: Tabulate the equilibrium conditi...
