Hcl ph value

WebpH = pOH = 7.00 If the pH is smaller than 7.00, the solution is an acidic solution; if the pH is larger than 7.00, the solution is an alkaline solution (remembering that this is strictly accurate only at 25°C). Correspondingly, acidic solutions are described by pOH values larger than 7.00 and alkaline solutions by pOH values smaller than 7.00.
