Due to their high buffer capacity humic acids neutralize acidic soils, which decimate acid caused stress in plant roots. Elements harmful for plants, especially aluminium and heavy metals, are bound firmly and immobilized by humic acids. Hence, their toxicity is reduced and phosphate bound by alumi...
The anion is stabilised and the N-H proton is readily lost.(ii)(iii) ions are less basic / weaker base than , as the corresponding acid, HBr is stronger than H₂O. Hence the ions are more likely to remove the N-H proton. OR ions are more basic / stronger base than , as the...
Oxides are compounds containing oxygen and only one other element.If the element other than oxygen is a nonmetal, the oxide is classed as a nonmetal oxide or an acidic anhydride. The latter name comes about because water added to nonmetal oxides under certain conditions produces acids. Likewise,...
that Brnsted-Lowry bases have in common with each other is that they have an unshared pair of electrons. When a hydronium ion comes wandering by the molecule, sometimes the lone pairs will reach out and grab it. An example of this is when ammonia accepts a proton in an acidic solution:...
Although thiols areweak acids, they are far stronger than alcohols. The sulfhydryl group is acidic enough to react with hydroxide ions to form thiolate salts. Thiolate anions are excellent nucleophiles. Where are thiols used? Thiols are usedas odorants to assist in the detection of natural gas(...
Acids are molecules able to donate a proton, H+ . Examples of acidic chemical compounds include hydrochloric acid, sulfuric acid, nitric acids, chromic acid, and acetic acid. pH:The pH of a solution measures the concentration of hydronium ions in a solution with a high concentration of ions ...
acidity can be defined as the concentration of hydrogen ions (H+) in solution. How acidic a solution is affects which reactions take place, and how quickly. The ability to control pH is crucial to successfully completing a large number of chemical reactions, and so buffer solutions have a va...
Amino acid substitutions at the TFIIS D282 and E283 residues, which are located in the acidic loop of TFIIS, lose the ability of transcript cleavage by RNAPII, resulting in increased levels of arrested RNAPII, a slow transcription elongation rate, and genome instability under unperturbed condition...
Which of the following compounds is most acidic? Please Explain.What acids make up acid rain?What are the six strongest acids in general chemistry?What kinds of ions do acids and bases form in water?Identify the following acids.Consider the acids: A = 1.6x10^-5 B = 9.0x10^-4 C = ...
It is a dimen- sionless number indicating the strength of an acidic or a basic solution [23]. Actually, pH of water is a measure of how acidic/basic water is [19, 20]. Acidic water contains extra hydrogen ions (H+) and basic water contains extra hydroxyl (OH−) ions [2]. As ...
