WebbThe scale of pH values is from 1.0 (highly acid) to 14 (highly alkaline) with 7.0 as the neutral point. Since the pH is logarithmic, each change of one pH unit means a tenfold change in the number of hydrogen ions. pH can be … WebbThe pH scale was developed by Danish chemist S ø ren Peter Lauritz S ø rensen (1868 – 1939) in 1909 and is generally presented as ranging from 0 to 14, although there are no theoretical limits on the range of the scale (there are substances with negative pH's and with pH's greater than 14, although for most substances the range of 0 – 14 suffices).
Webb19 juni 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 … Webb10 sep. 2024 · If you use methyl orange, you expect the color to change from yellow to orange somewhere below a pH of 6 and from orange to red around a pH of 4.
