How Much Water and NaOH Is Needed to Make a PH of 11.0?

Oct 13, 2015 · The sodium sulfate comes out of solution in high sodium hydroxide concentration and by doing forms a protective layer on the surface of the plate. Also keep the lowest T.D.S level. (Total dissolved suspended & solid) What is pH value for boiler water? It is the l ogarithm of reciprocal of hydrogen iron concentration.

Boiler Water Treatment - Home - Association of Water

Caustic soda (NaOH) is the only normal boiler water constituent that has high solubility and does not crystallize under typical boiler conditions. Its caustic concentration can be as high as 10,000-100,000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If the "free hydroxide …

pH Adjustment and Neutralization, the basics

In order for this reaction to take place it is important to maintain a pH at a minimum value of 9.50. It is desirable to keep the concentration of phosphates in the water to 30 - 50 PPM in order for complete reaction of the phosphates with the calcium hardness entering the boiler through the feedwater.

Inferred pH in Steam Plant Water Chemistry Monitoring

Inferred pH is possible only in caustic-based boiler treatments. Sodium hydroxide is a strong base. It dissociates completely in water according to the equation: NaOH(s) → Na+ + OH-As the equation shows, adding sodium hydroxide to water changes both the pH and the conductivity. Figure 3 …

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 waterso in reality, you'd add a bit more - but still, we're talking tiny specs of hydroxide vs pounds.
