38° Bé Sodium Hydroxide NaOH
SG = 145 / ( 145 - Bé ) = 145 / ( 145 - 38 ) = 145 / 107 = 1.355
If you look at the data of Sodium Hydroxide you will see that a S.G of 1.355 represents a concentration of approx. 33 % Weight

What is the pH level of muriatic acid?
Muriatic acid is a very strong acid. The pH will vary depending on the concentration of the acid. A 10% concentration (by weight) has a pH of around -0.5 while a 38% concentration has a pH of around -1.1. I found this information at: http://en.wikipedia.org/wiki/Muriatic_acid.
Why hcl is 37 percent pure only?
HCl is usually prepared by dissolving Hydrogen Chloride into water, but as we increase the concentration of HCl its boiling point starts to decrease (10% HCl has boiling point of 103 C and 38% has 48 C), so at concentration over 38 the rate of evaporation becomes so high that extra precautions has to taken for storage and handling (like low temperatures and high pressure), Thats why it is not safe to produce HCl over 40%. And as the rate of evaporation at even 38% is quite high it is called fuming HCl acid.
What are safe hydrogen sulfide levels in chlorine swimming pools?
That's "Sulfuric Acid" to the rest of us . Depending on the concentration you use(Mine is 38%). Never more then 12ozs per 20,000 gallons.
If a segment of DNA has 20 adenine in its base composition what percent thymine is there?
The concentration of A must be equal to the concentration of T and the concentration of G must be equal to the concentration of C. This is because of the base pair rules that state that A pairs with T and G pairs with C. If you have a gene where [A] is 20%, this means that [T] also equals 20%. This puts the total concentration of A and T at 40%. Therefore the concentration of G and C is 100-40 which is 60%. This means that the concentrations of G and C are each 30%. []=concentration
