pH Meter

  PH Meter Question 1)  What is full form of pH?   Answer) pH is denoting,  potential of hydrogen or  power of hydrogen Question 2) what is pH value or pH scale.? Answer)  pH is a scale used to specify the acidity or basicity of an aqueous solution:   lower pH values correspond to solutions which are more acidic in nature while higher values  correspond to solutions which are more basic or alkaline. pH is the negative of the base 10 logarithm of the activity of the hydrogen ion the pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution. A  lower pH indicates the higher concentration of hydrogen ions at 25 C° solutions with the pH less than seven are acidic and solutions with the pH greater than seven are basic. Question 3) what is equation of pH? Answer) PH is defined as the negative logarithm of the hydrogen ion activity. pH=-log 10   ( H +) Question 4) How to measure pH? Answer)  Answer) Primary pH standard values are resolute using a c
