It depends on the concentration. pH is the negative log of the concentration of H+ atoms in a solution (measured it molarity, mol/L). Phosphoric acid (H3PO4) has 3 Hs in it, so for every molecule of acid dissolved, there are 3H+ ions.
But Phosphoric acid isn't a strong acid, so it doesn't completely dissolve in water. You can tell whether an acid is strong or not by looking at the number of Os and Hs. If it has 2 more Os than Hs, it is strong.
One must look up how thoroughly the acid dissolves in water. By looking it up on wolframalpha, I find that for every mole of H3PO4
In the solution, 1.06 moles of H+ are present. So if I take the -log1.06, I find the pH of 1M phosphoric acid, which is 1.1.

What pH of phosphoric acid?
The pH of phosphoric acid will vary depending on its concentration. For a 1 M solution of phosphoric acid, the pH will be around 2.1.
What pH is phosphoric acid?
The pH of phosphoric acid at a concentration of 1 mole per litre, is 1.08
What is the pH level of phosphoric acid?
The pH level of pure phosphoric acid is typically around 2.8.
What is the pH of phosphoric acid?
The pH of an acid depends completely on the concentration of the acid, thus, an extremely concentrated solution of phosphoric acid will have a low pH, and a less concentrated solution (as in some soft drinks) would have a slightly higher pH.
Is cola an acid alkali or neutral?
Coke is an acid with a PH value of 2.525.

How do you calculate concentration of phosphoric acid?
To calculate the concentration of phosphoric acid, you need to know the volume of the solution containing phosphoric acid and the amount of phosphoric acid in moles present in the solution. By dividing the amount of phosphoric acid in moles by the volume of the solution in liters, you can calculate the concentration in units of moles per liter (Molarity).
What is the pH of phosphorus oxide?
Phosphorus oxide does not directly produce a pH value as it is not an acid or base in the traditional sense. However, when phosphorus oxide reacts with water, it forms phosphoric acid, which can result in a decrease in pH.
How can you find the pH of phosphoric acid that is complelely ionized using the 3 equations?
To find the pH of completely ionized phosphoric acid, first determine the concentration of the hydronium ions (H3O+) by using the molarity of the phosphoric acid solution. Then, calculate the pH using the equation pH = -log[H3O+]. Since phosphoric acid has three dissociable protons, the pH would be dependent on the concentration of H3O+ from the complete ionization of the acid.
How does coke and coco cola get acid?
They contain phosphoric acid. They have a pH of around 2.4
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.
Which is stronger sulphuric acid and phosphoric acid?
It is not a contest here. These are both strong acids; which means they disassociate almost 100% in solution.
Phenolphthalein would not be an appropriate indicator to use to determine the Ka1 of phosphoric acid Why What indicator would be appropriate?
Phenolphthalein is not suitable for determining the Ka1 of phosphoric acid as it changes color at a pH around 8-10 while the Ka1 dissociation of phosphoric acid occurs at a much lower pH of around 2. A suitable indicator for determining the Ka1 of phosphoric acid would be methyl orange, which changes color in the pH range of 3.1-4.4, closer to the pH range of the dissociation of the first hydrogen ion from phosphoric acid.
