Phosphoric acid (H3PO4) is a weak acid with a dissociation constant (Ka) of approximately 7.5 x 10^-3. When dissolved in water, phosphoric acid will partially ionize to form H+ ions and H2PO4- ions.
The addition of water to phosphoric acid will dilute the solution, causing the concentration of H+ ions to decrease. This will result in a decrease in pH levels, making the solution less acidic.
Therefore, adding water to phosphoric acid will cause the pH levels to increase.
Will water cause H3P04 to increase or decrease ph levels
