WebBecause of that, if there's any effect of piranha solution on silica, it'll be the same as any other acid. At most it'll donate a H⁺ to some silica oxygen on the surface through this: R-O-R' + H⁺ --> R-OH⁺-R' R-OH⁺-R' --> R-OH + R'⁺ R'⁺ + H₂O --> HO-R' + H⁺ The H⁺ isn't even consumed, it's just catalyzing the reaction. incoming phone call sound effectWebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.
