WebIn chemistry, pH (/ p iː ˈ eɪ tʃ /), also referred to as acidity, historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a scale used to specify the acidity or basicity of an aqueous solution.Acidic solutions (solutions with higher concentrations of hydrogen (H +) ions) are measured to have lower pH values than basic or alkaline solutions. WebSubstances with high pH (from 8 to 14) are bases. Bases you can find around the house include things like bleach and baking soda. According to the chart above (in blue), bleach has a pH of 13, while baking soda has a pH of 9.5. This means that bleach is more basic than baking soda. Higher pH values mean that something is more basic. easy_refresh使用
