1. pH 值(溶液或物质的酸碱度。pH 值介于 0 至 14,7 以下为酸,7 以上为碱)a measurement of the level of acid or alkali in a solution or substance. In the pH range of 0 to 14 a reading of below 7 shows an acid and of above 7 shows an alkali ....
Litmus or pH paper is filter paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid (acidity) or base (alkalinity) exists in a solution. You might have even used some to test whether the water in a swimming pool is...
