What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
What is the pH of a solution with H 10-10m?
[H+] = 1 x 10-10 M then pH = 10
What is the net charge of phosphatidylserine at pH 6.0?
- 1
What paired with cytosine?
guanine
What is the concentration of hydrogen ions in a pH equals 1 solution how does it differ from a solution of pH equals 2?
Remember: by definition the concentration of hydrogen ions (in mol/L) is equal to 10 to the negative power of the pH value (pH).[H+] = 10-(pH)Using this we find that: [H+] = 10-1.0 = 0.1 for pH = 1.0 and[H+] = 10-2.0 = 0.01 for pH = 2.0 , thus 10x smaller!
The pI of a lysozyme is 11. What is the pH range in which the overall charge of the lysozyme is positive?
At pH values less than the pI point the net charge is positive. If at pH above the pI poiint, the charge will be negative.
A pH of 10 is what?
A pH of 10 is a base.
What is the charge on the perchlorate anion?
The pH depends on the concentration (how much is dissolved in a given volume of water) Since it is a strong monoprotic acid the pH equals the negative logarithm of its molar concentration. A 1M solution has a pH of 0 a .1M solution has a pH of 1 and so on until a pH of about 7.
Net charge of histidine in pH 1 3 5 11?
pK1 = 2.3, pKr = 6, pK2 = 9.7 (all approximate) at physiological pH, histidine has no net charge. at pH 1, below all pKas and charge is +2 at pH 3, amine group proton pops off, so +1 charge at pH 5, still below 6 and above 2.3 so +1 charge if had pH above 6, for instance... at pH of 8 net charge is zero, or neutral... such that it is neutral at physiological pH (a bit above a pH of 7) at pH 11, exceeds all pKas of amine, acid group, and R group. So net charge of -1 amine deprotonation, carboxylic acid deprotonation, and R group deprotonation happen pH 11 because it exceeds all pKs
A pH of 10 is an acid or base?
A pH of 10 is definitely a Striong Base.
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always
At Ph 10 what charge would Zwitterion ion have?
it would depend on amino acid in question. pH above amino acid pI, zwitterion will carry net negative (-) charge. at pH below pI, zwitterion will carry net positive (+) charge. depending on the amino acid, some have more than one acidic or basic functional group. such functional groups can make the amino acid vary in net charge from 2- to 2+ if not more.
Is the pH 10 an acid or alkali?
A pH of 10 is alkaline or basic. An pH above 7 is alkaline.
How much stronger is a pH of 10 when compared to a pH of 8?
A pH of 10 is 100 times more basic as something with a pH of 8
What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
What charge does pH 4 have?
Plus charge, ie, it has H3O^+ ions (hydronium ions)
What is charge of aspartame if dissolved in pure ammonia pH 12.0?
The charge of aspartame will be positive
