It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.

The small size and fast response of the ISFET sensors enable measurement of about 2.0 mL of sample solution over a measurement period of 120 s. The 90% response time is within 2 s.
WebbThe pH value describes the activity of hydrogen ions in aqueous solutions typically on a scale of 0 to 14. Based on this pH scale, liquids are characterised as being acidic, alkaline or neutral: a solution which is neither acidic nor alkaline is neutral. This corresponds to a value of 7 on the pH scale. Was this answer helpful? 0 0 Webb2 mars 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 …

WebbThe concept of pH is a quantitative measure of acidity or basicity of an aqueous or any other liquid solution. The concept of pH involves using the pH scale for measuring the acidity or alkalinity of any solution. The pH scale ranges from 0-14. This concept of pH and pH measurement was developed first by a Danish Scientist.
