Dec 01, 2017 · In logarithmic form: pH + pOH = 14. Hence pH = 7 & pOH = 7. If the pH of solution is < 7, the solution is called acidic such as HCl, H2SO4, HNO3, H3BO3, etc and if the pH > 7, the solution is basic such as NaOH, KOH, NH4OH, Ca (OH)2 etc. pH can be measured by the following methods: (i) Colorimetric method (pH-paper/indicator)
