Thiss has only started after my latest update earlier this week. This seems to be the only website where I get this message. Can someone please tell me who is cloudflare, why am I getting this message and how do I fix this.
In chemistry, pH (/piËËeÉªtÊ/) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the logarithm to base 10 of the molar concentration, measured in units of moles per liter, of hydrogen ions.
pH is a measure of the acidic or basic (alkaline) nature of a solution. The concentration of the hydrogen ion [H+] activity in a solution determines the pH.Mathematically this is expressed as: pH = - log [H+]. The pH value is the negative power to which 10 must be raised to equal the hydrogen ion concentration.or example, 4 mg/l of iron would not present a toxic effect at a pH of 4.8. However, as little as 0.9 mg/l of iron at a pH of 5.5 can cause fish to die. Synergy has special significance when considering water and wastewater treatment.
