Ph of solution with 8.5 an 3.4
WebThe pH of a solution is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH +. [15] Mathematically, pH is expressed as: For example, for a solution with a hydrogen ion activity of 5×10 −6 (i.e., the concentration of hydrogen ions in moles per litre), the pH of the solution can be calculated as follows: WebThe scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered …

WebThe 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. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
Web15.11: Determining the pH of Salt Solutions. The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7.
