There are multiple ways of measuring the pH value of a solution, one of which is to use indicator paper. Indicator paper changes color depending on the pH of the solution applied to it, and by comparing to a chart a fairly accurate measure of the solution's pH can be obtained. If a more accurate measure is needed, a glass electrode can be used, which works by measuring the conductivity of the solution.
Bide desberdin asko daude soluzio baten pH balioa neurtzeko, hauetariko bat paper adierazlea erabiltzea da. Paper adierazlearen kolorea aldatu egiten da aplikatzen zaion soluzioaren pH- aren arabera, gero kolore hori diagrama batekin konparatzen da, soluzioaren pH balioaren neurri nahiko zehatza lortuz. Neurketa zehatzagoa behar bada, beirazko elektrodoa erabil daiteke, soluzioaren eroankortasun neurtuz funtizonatzen du.
