WebMar 20, 2024 · The pH scale is used to measure how acidic or alkaline a substance is. This scale ranges from 0-14, with seven being neutral. Substances with a pH below seven are acidic, and substances above seven are alkaline. The lower the pH number, the more acidic the substance is.
WebFeb 6, 2024 · Values between 0 and 7 indicate an acidic solution. Values between 7 and 14 indicate a basic solution. A pH of exactly 7 indicates that a solution is neutral, neither acidic or basic. Pure water is usually pH 7. The pH scale is shown below. The lower the pH value, the more acidic the solution; the higher the pH value, the more basic the WebThe basic pH scale extends from 0 (strong acid) to 7 (neutral, pure water) to 14 (strong caustic). Chemical solutions with pH levels below zero and above 14 are possible but rare. pH can be measured by measuring the voltage produced between two special electrodes immersed in the liquid solution.
WebFeb 10, 2014 · The pH scale may seem small, but each whole number represents a ten-fold leap in concentration of either H ions or OH ions. For example, rain is slightly acidic with a pH that measures about six. A grapefruit is approximately three on the pH scale. That means that a grapefruit is 1,000 times more acidic than rain.
