WebIf you plug the hydrogen ion concentration of water (1 × 10 ^ {-7} −7 M) into this equation, you’ll get a value of 7.0, also known as neutral pH. In the human body, both blood and the cytosol (watery goo) inside of cells have … WebApr 9, 2024 · We know that the total volume is 100 mL, so: V A− ≈ 100 −V HA in units of mL Therefore, we now have: 0.6310 = 0.240 M × (100 −V HA) 0.100 M ×V HA For ease of notation, let x = V HA. Then we have implied units: 0.6310 = 0.240(100 − x) 0.100x = 24.0 − 0.240x 0.100x 0.0631x = 24.0 −0.240x (0.0631 +0.240)x = 24.0 ⇒ x = V HA = ( 24.0 0.0631 …
