WebApr 23, 2024 · This gives: x2 −(3 × 10−7)x +10−14 = 0. If we apply the quadratic formula, ignoring the absurd root we get: x = 0.385 × 10−7xmol/l. ∴ [H+] = 2 ×10−7 − 0.385 ×10−7 = 1.615 × 10−7xmol/l. pH = −log[H+] = −log[1.615 × 10−7] = 6.79. As we would expect, the solution is very slightly acidic. pH +pOH = 14. ∴ pOH = 14− ... WebCalculate the pH of 10 -8 M HCl. Calculate the pH of 10. -8. M HCl.
