To effectively solve polyprotic acid problems, one should first identify the number of acidic hydrogen atoms in the acid. Then, calculate the equilibrium concentrations of each protonated form of the acid using the acid dissociation constants (Ka values). Finally, use the mass balance and charge balance equations to determine the concentrations of all species in the solution.
The formula for a common polyprotic acid, like sulfuric acid, phosphoric acid, or carbonic acid, typically includes multiple hydrogen atoms that can each be ionized to release protons in solution. These acids can donate multiple protons in a stepwise manner, leading to their classification as polyprotic.
To effectively solve buffer problems, one should first identify the components of the buffer solution (acid and conjugate base), calculate the initial concentrations, and use the Henderson-Hasselbalch equation to determine the pH. Adjusting the ratio of acid to conjugate base or adding more buffer solution can help maintain a stable pH.
No, acetic acid (HC2H3O2) is a monoprotic acid because it can donate only one proton (H+) per molecule in a chemical reaction. Polyprotic acids can donate more than one proton.
An acid which has the capability of donating not just one, but TWO H+ to a base during an acid-base reaction. eg. Sulfuric acid and excess water H2SO4 + H2O --> HSO4- + H3O+ THEN: HSO4- + H2O <--> SO4^2- + H3O+ (note the reversible arrow for the second one) POLYPROTIC acids: diprotic - can donate 2 hydrogen cations per molecule triprotic - can donate 3.. etc.
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-

Yes, H3PO4 (phosphoric acid) is a weak acid. It is a polyprotic acid, meaning it can donate multiple protons in a stepwise manner, resulting in a gradual decrease in acidity with each proton donated.
In the titration of a polyprotic acid, the successive equivalence-point volumes decrease because each equivalence point corresponds to the complete neutralization of one acidic proton. This leads to a decrease in the moles of acid present in the solution, requiring less titrant to reach the subsequent equivalence points.
To determine the pH of polyprotic acids, one can use the stepwise dissociation constants of each acidic proton and calculate the concentrations of the acid and its conjugate base at each stage of dissociation. By considering the equilibrium concentrations of the acid and its conjugate base, one can then use the Henderson-Hasselbalch equation to calculate the pH of the solution.
Look up the word "polyprotic" in your assigned reading, and the answer will be self-evident.
Because KOH is potassium hydroxide, you can recall that in biology you must have learned about H+ being and acid and OH- being a base and K(OH) contains the one hydroxide making it a base, not an acid.
Yes, acid can effectively kill fungus.
