Is h2po4 stronger or weaker than hpo42?
H2PO4 is stronger than HPO42 because it has a higher concentration of H+ ions, making it more acidic. H2PO4 has one more hydrogen ion to donate compared to HPO42, which gives it greater acidic strength.
Why imides are more acidic than amides?
Imides are more acidic than amides because the hydrogen atom in imides is present on a nitrogen atom that is more electronegative than the oxygen atom in amides. This greater electronegativity leads to a more stable conjugate base after deprotonation, making the imide more acidic.
Is pH 9 more acidic than pH 4?
No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.
Which one is more acidic milk of magnesia or household amonia?
Neither is acidic, both are basic. But milk of magnesia is less basic and therefore more acidic.
What compound is more acidic Mn2O7 or MnO2?
Mn2O7 is more acidic than MnO2. This is because Mn2O7 is a peroxide compound that contains more oxygen atoms and can release more H+ ions when dissolved in water, making it a stronger acid than MnO2.
What are the relative acidities of H3PO4 and H2PO4 -ion?
H3PO4 > H2PO4-PH 0.1 M SolutionsH3PO4 PH=1.5H2PO4- PH=4.4HPO42- PH=9.3PO43- PH=12
Conjugate acid of HPO4 2?
H3PO4==============Phosphoric acid.
What is the conjugate acid of HPO43?
'Conjugate' means ONE proton more (acid) or less (base) than the described acid or base respectively:So the conjugate acid of PO43- (phosphate) is HPO42- (monohydrogen phosphate)
Is h2po4 stronger or weaker than hpo42?
H2PO4 is stronger than HPO42 because it has a higher concentration of H+ ions, making it more acidic. H2PO4 has one more hydrogen ion to donate compared to HPO42, which gives it greater acidic strength.
What is the pH level of HPO4?
The pH level of HPO4 (dihydrogen phosphate) depends on its concentration in solution. In general, HPO4 tends to be weakly acidic, causing the solution to have a pH below 7. At low concentrations, the pH may be closer to neutral, while at higher concentrations, it will be more acidic.
What is a poly protic acid?
A polyprotic acid can (in a multi-step reaction) donate more than one proton per molecule of acid.E.g. phosphoric acid can do 'the trick' three times:H3PO4 --> H+ + H2PO4-H2PO4- --> H+ + HPO42-HPO42- --> H+ + PO43-
How do prepare phosphate buffer pH 4.5?
To prepare a phosphate buffer at pH 4.5, you can mix potassium dihydrogen phosphate (KH2PO4) and disodium hydrogen phosphate (Na2HPO4) in specific ratios based on their pKa values. The exact ratio will depend on the desired pH and buffer capacity. Typically, you would mix the two components in distilled water, adjust the pH with acid or base as needed, and then dilute to the desired volume.
Is HClO4 or H3PO4 stronger?
HClO4 (perchloric acid) is stronger than H3PO4 (phosphoric acid) because it has a more acidic proton which can dissociate more readily in water, leading to a higher concentration of H+ ions in solution.
Chemical name of phosphoric acid?
The formula* for phosphoric acid is H3PO4.*Compounds do not have "symbols" in the chemical sense; only atoms do. The formula itself, of course, is a symbol for the compound itself in a more general meaning of "symbol".
What more acidic of two solutions has?
The more acidic of two acidic solutions has more H+ ions per liter.
Hemoglobin has a tendency to release oxygen where?
Ph is more acidic.
What is the name for HPO42?
HPO4 does not exist. HPO42- would be the dibasic form of phosphoric acid and be the hydrogen phosphate ion. H3PO4 also exists and is phophoric acid. So if two moles of NaOH were reacted with phosphoric acid 2Na+ HPO42- would be formed disodium hydrogen phosphate.
