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 acid and mix it with water, acetic acid will donate a proton. If you mix in add a ...
Why is it sensitive to pH? Why is the pH of the ocean higher than the pH of lakes? Why? Why is the pH range so tightly controlled by the body? Describe where common substances belong on the pH scale. Why is it important to know the pH when conducting experiments to measure ...
The pH scale is a scale from 0 to 14 that tells us how acidic or basic a substance is. Substances with a pH lower than 7 are acidic, and those with a pH higher than 7 are basic. Substances with a pH of exactly 7 are considered to be neutral....
When computing the shift in a quantity such as a cross section from its SM value, one must therefore take care to include the contributions from these parameter shifts. Concretely, if\sigma _{\text {SM}}(g_i)is a cross section computed in the SM written as a function of the parameters...
b) If you added Thymol blue to a solution of pH 5 what color woul A certain indicator HIn has a pKa of 3.00 and a color change becomes visible when 7.00% of the indicator has been converted to In-. At what pH is this color change visi...
Firstly, the pH levels in animal intestines (approximately pH ≥ 6) are typically higher than the pKa of MHA, meaning that MHA would be present essentially in its anionic form and would therefore require transporters (rather than diffusion) for uptake. Secondly, the transport of MHA via ...
Host: This is fascinating. You are saying something like Hinglish, kind of becomes a language that’s natural rather than being synthetic. Kalika: Yes. Monojit: Yes. Host: Wow! Ok. Kalika: I mean, if you think of a mother tongue as the language that you dream in and then ask...
(>10 g/day) during creatine supplementation [49]. There appears to be an unsubstantiated perspective that if the kidneys are “forced” to excrete higher than normal levels of creatine or creatinine, some sort of kidney “overload” will take place, causing kidney damage and/or renal ...
If a solution has a pH of 8.02, what is its (H3O+) and (OH-)? Is the solution acidic or basic? A solution has an (H3O+) of 3.5 x 10-3. What is the (OH-) and pH? Is it acidic or basic? A solution has an (H3O+) of 1.8 x 10-9. What is the (...
If the pKa of HA was 4.8 and the pKa of BH+ was 10.3, what would be the value of the equilibrium constant? Two pKa values are reported for malonic acid, a compound with two COOH groups. Explain why one pKa is lower and one pKa is higher than the pKa of ...
