boiler water sodium hydroxide to regulate ph

How much Sodium Hydroxide needed to raise boiler water pH ...

Sep 28 2015 · If you go 'by the book' 1 gram of pure sodium hydroxide (about the weight of a penny) would move 1060 gallons of water from 7.0 to pH 8.8. (then you need about 20 grams to get to pH 10.0) This assumes there is nothing buffering the water...so in reality you'd add a bit more - but still we're talking tiny specs of hydroxide vs pounds.

Hot Water Boiler Chemical Guide - ChemWorld

Chemically treating a boiler is very easy but often overlooked. First we define a hot water boiler as a boiler that generates minimal steam with no condensate return loss or a boiler that produces no steam at all. Types of Boiler Chemicals for Hot Water Boilers By far the most popular hot water boiler chemical is a sodium nitrite blend. This chemical blend often contains a low percentage of borate silicate tolytriazole and sodium hydroxide.

The Effects of Temperature on the pH of Water | Sciencing

Apr 26 2018 · A solution can only become more acidic if there is a higher level of hydrogen ions than hydroxide ions. In the case of pure water the concentration of hydrogen ions and hydroxide ions never changes so water is always neutral regardless of whether its pH level changes. At room temperature (25 degrees Celsius) the pH of pure water is 7.

pH and alkalinity - Water Treatment and Purification

When sodium hydroxide enters the water it will separate into sodium and hydroxide ions (NaOH à Na+ + OH-). When an acid substance ends up in water it will give up a hydrogen ion to the water. The water will than become acid. The number of hydrogen ions that the water will receive determines the pH.
