Hydrofluoric acid $\left( {HF} \right)$ is not a strong acid but instead, it is a weak acid. It fails to dissociate completely in water, because of that it is classified as a weak acid. It is against the definition of a strong acid. Usually, if we look at fluorine it has a ...
Hydrochloric acid HCI is a strong acid. About what pH would you expect it to be? The weak acid hippuric acid is 5.0% ionized at pH 2.3. What is the pKa of the hippuric acid? Why is HF a weak acid, but HCl is a strong acid?
Or, to put it another way, pKa is to Ka, what pH is to proton concentration. And we just said that the larger the value of Ka, the stronger acid we are dealing with. This relationship gets reversed when we take the negative logarithm to calculate pKa. ...
What is the pH at the equivalence point of a weak acid-strong base titration? Wouldn't the pH be greater than 7? What is the pH of pure water when tested with a pH scale? What does the pH measure? 1. What is the pH of 1 x 10-8 M HCl 2. What is the pH of 1 x ...
Crh proteins catalyze crosslinking of chitin and glucan polymers in fungal cell walls. Here, we show that the BcCrh1 protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense. BcCrh1 is localize

b, CB1 cell lysate was electrophoresed and transferred onto a nitrocellulose membrane. Two sets of the membrane were treated with recombinant full-length LHPP (for 4 h) in TMD buffer (see Methods) and the other set of the membrane was treated with plain TMD buffer (pH 8.5). Immuno...

Lung leukocytes (1 × 106) were collected after a 48 h treatment with Cd and lysed in 10 mmol/L HCl. After precipitating the protein with 5% sulfosalicylic acid, the GSH level was quantified in the supernatant using 5,5'-dithio-bis-[2-nitrobenzoic acid] (DTNB) in Tris-HCl (pH 8.9) ...
19. It has been hypothesized that the NMR HMM-HA evolved to provide strong and elastic skin in adaptation to squeezing through the subterranean burrows20. If this hypothesis is correct, one would expect HMM-HA to be found in other subterranean mammals. Remarkably, unique amino acid changes ...
