How do you balance P4O10 plus H2O equals H2PO4?
P4 3o2 ---> 2po5
How many grams of H3PO4 are in 265 ml of a 1.50 M solution of H3PO4?
To find the grams of H3PO4 in 265 ml of a 1.50 M solution, you first calculate the moles of H3PO4 using the molarity (1.50 mol/L) and volume (0.265 L), then convert moles to grams using the molar mass of H3PO4 (98.0 g/mol). Therefore, there would be approximately 39.2 grams of H3PO4 in 265 ml of the solution.
What is h2po4 in chemistry?
H2PO4- is called dihydrogen phosphate ion. It is the conjugate base of Phosphoric Acid H3PO4 and the conjugate acid of monohydrogen phosphate ion HPO42-Liquid
Phosphoric acid H3PO4 has three dissociable protons with pkas 2.14 and 6.86 and 12.4 which form of the acid predominates in a solution of pH 4?
pH = 4 is about in the middle (4.7) of the values pH=pKa,1 and pH=pKa,2.This is an indication of H2PO4- abundantly being present, becauseat pH=2.14 it is halfway forming its conjugate acid H3PO4 andat pH=7.21 it is halfway forming its conjugate base HPO42-
What is the pH of H3PO4?
The pH of H3PO4 (phosphoric acid) depends on its concentration. For a 1M solution, the pH would be around 0.91. Since phosphoric acid is a weak acid that can donate three protons, its pH decreases with increasing concentration due to the dissociation of H+ ions.

What is the conjugate base for HPO3 -2?
H3PO4 (aq) + H2O (l) ---> 2H3O+ (aq) + PO4-3 (aq)donor acid + acceptor base ---> conjugate acid + conjugate basethe answer above is wrongto form a conjugate, the ion H2PO4 - must lose a hydrogen ion H+i.eH2PO4 - -H+ = HPO4 2-(conjugate base)
How many moles of O2 are in one mole of H3PO4?
Actually H3PO4 is a molecular formula referring to the compound we know as Phosphoric acid. It doesn't indicate number of moles of H3PO4. But the number of moles can be found out if the amount in mass or some other measurable quantity(e.g. conc. in solution) is given. The molar mass(mass of 1 mole) of H3PO4 is 98 grams. So if mass is given then it can be converted to grams and dividing by molar mass(i.e 98) we get number of moles. moles of H3PO4 =(mass of H3PO4 in grams)/98. 1 mole of H3PO4 has ->3 moles of H atoms. ->1 mole of P atoms. ->4 moles of O atoms. ( 1 mole=6.0225 *1023 units)
How many ml of 0.10 m naoh solution are needed to neutralize 15 ml of 0.20 m h3po4 solution?
90. mL NaOH, remember there are two sig figs in this problem not one, hence the decimal point after the 90.
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.

What type of reaction is h3po4 plus 3koh equals k3po plus 3h2o?
Your reaction is this...H3PO4 + 3KOH --> K3PO4 + 3H2OThis type of reaction is called a double replacement.Note: You didn't put a 4 on the oxygen on the phosphate group on the product side in your question. If it wasnt there the equation would not have been balanced so i put it in myself.
