Ortho nitrophenol is more volatile than para nitrophenol becauseO-Nitrophenol has intramolecular hydrogen bondingwhereas para nitrophenol has inter molecular H bonding and so boils relatively at higher temperature. Why is Ortho Nitrophenol more acidic than meta nitrophenol? An inductive effect is an electr...
What is the pH of a solution that has an OH- of 1.3 x 10-4 M? Is this more or less basic than pure water? What is the pH of 1.85 g of HCN (MM=27.02) dissolved in 3.50 L of water? What is the pH of an acidic solution that has a hydrogen ion concentra...
Acidity is a property of a given atom or functional group that determines how well the group can stabilize a charge that will be present upon the donation of electrons from a Lewis base. The more stable the conjugate base of the acid is, the more acidic the compound. ...
The more readily it does this, the more acidic the chemical or functional group is. Every chemical has a unique pKa value (or set of pKa values if it can donate more than one proton). It’s important to remember that acidity is relative. If you take a weak acid such as acetic ...
Hint: The buffer capacity of a buffer solution is a measurement of its magnitude of its resistance to change in pH on addition of an acid or a base, buffer capacity depends on the ratio of salt and acid, if a buffer solution has higherconcentrationits buffer capacity will be greater....
Substantial evidence has indicated that cancerous cells require a higher level of copper compared to healthy cells3,4,5. Simutaneously, high expressions of cyclin B1 and CDK1 are associated with more aggressive cancer phenotype and are considered major contributors to CDK1-driven G2/M transition...
Thus a pH of 2 is ten times more acidic than a pH of 3—and a pH of 2 is 100 times more acidic than a pH of 4. If this seems confusing, consider another logarithmic scale, the Richter Scale, where an earthquake measuring 7 is ten times stronger than a 6. Liquid required: A ...
Three domains of moderate hydrophobicity of 18 (aa 243–260; H1), 23 (aa 320–342; H2), and 16 (aa 349–364; H3) amino acids are located in the center of the sequence surrounding a highly acidic domain (aa 291–318) where 19 of 28 consecutive amino acids are glutamic or aspartic ...
pH < pKa mostly protonated Henderson-Hasselbalch equation pH = pKa + log [A-]/[HA] describe the effects of hypoventilation using the bicarbonate buffer system? -hypoventilation is increased CO2 levels-a shift to the right-end result: increased H+ -> decreased pH -> more acidic"respiratory ac...
Greater preponderance of the up conformations on mutated S proteins have been linked to higher infectivity, but at the expense of more vulnerability to neutralising antibodies13. Distal mutations from the binding region have also been found to affect structural stability of the S protein and its ...
