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.
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.
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.

How does coke and coco cola get acid?
They contain phosphoric acid. They have a pH of around 2.4

Which is stronger sulphuric acid and phosphoric acid?
Sulfuric acid is stronger than phosphoric acid. Sulfuric acid is a strong acid while phosphoric acid is a weak acid. Sulfuric acid is more corrosive and has a lower pH compared to phosphoric acid.
Is cola an acid alkali or neutral?
Cola is acidic due to the presence of carbonic acid from carbonation, citric acid from flavorings, and phosphoric acid from additives like phosphoric acid.
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.
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 fanta?
The pH of Fanta ranges from 2.4 to 2.9, making it acidic due to the presence of citric acid and phosphoric acid in the ingredients.
What is the pH level of flat coke?
It is slightly acidic because contain phosphoric acid.
