So you can imagine, with a lot of water in a product it creates a higher PH value.We are all familiar with the so-called all-in-one shampoo and shower gel products. These products often have an even higher PH value of 8 or sometimes even 9.
WebThis pH value of 7 is important because it indicates a neutral solution. All other substances are compared to this neutral point. Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic. Common mistakes and misconceptions Acids are not always dangerous. WebNote that the pH at the equivalence point of this titration is significantly greater than 7, as expected when titrating a weak acid with a strong base. (c) Titrant volume = 12.50 mL. This volume represents one-half of the stoichiometric amount of titrant, and so one-half of the acetic acid has been neutralized to yield an equivalent amount of ...
WebExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less than 7 whereas for bases it is greater than 7.
