Indicator liquid for determining the pH value of water and some transparent liquids.

With the colored indicator liquid you can quickly and easily determine the pH value of water and some other transparent liquids. Add 2-3 drops of the indicator liquid to the aqueous solution whose pH value you would like to measure. Adding the drops causes a color change. The pH value can be determined using the included pH scale. Light red is considered highly acidic. Light purple as strongly alkaline. In terms of accuracy, this type of measurement is absolutely sufficient for domestic use. By the way: The abbreviation "pH" is derived from the neo-Latin "potentia Hydrogenii", which means "concentration of hydrogen". The pH can range from 0 (extremely acidic) to 14 (very alkaline). The following applies: • pH value < 7 = acidic • pH value = 7 = neutral • pH value > 7 = alkaline (basic) Important instructions: - The pH indicator liquid must NOT be ingested. Neither pure nor diluted. It is strongly recommended that the liquid be kept safely away from children. - The pH value of alkaline water cannot be measured with conventional pH indicator paper! - The scope of delivery includes an indicator liquid and a color scale with the different pH values.
