The water quality of fountain equipment shall not exceed 15 degrees, and shall not render any other colour, with turbidity not exceeding 10 degrees. Shall not contain visible matter. The impurity content of water is less than 0.1%, impurity particle size less than 0.2 mm, chlorine ion content...
To answer the question about the type of chemical reaction that occurs when chlorine is involved in bleaching, we can break it down into several steps:1. Understanding the Reaction: When chlorine is used for bleaching, it typic
to 14, where anything below pH 7 is considered acidic, anything above pH 7 is considered basic, and a pH 7 is considered to be neutral. pH indicators are used so that the pH of a solution can be determined visually. pH in...
the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water. The water and solution should also be replaced each day...
Another method used in advanced wastewater treatment is chlorination; chlorine is among the most common methods used to disinfect wastewater effluents before discharge into streams (Hladik et al., 2014), rivers (Bellanca et al., 1977), or agriculture (Ferro et al., 2015). As a well-establishe...
Reactive dyes is generally poor fastness to chlorine, mainly depends on the molecular structure of the hair color body, diazo dyes base of ortho sulfonic group, or carboxylic acid base, or in the coupled components of hydroxy ortho or para sulfonic group, or carboxylic acid base, because of ...
