What is the pH range of a strong but dilute acid?
It depends on just how dilute it is. If we're talking about a strong acid - in this case, acids like perchloric (HClO4), sulfuric (H2SO4), or nitric (HNO3) - and assume that the acid dissociates completely (an ideal situation; in sulfuric acid's case, only the first proton is assumed to dissociate), the pH of the acid is the negative logarithm of its molarity. For example, if you have 1 × 10-3 M (.001 mol · L-1) hydrochloric acid (HCl), its pH will be -log(1 × 10-3) = 3. (Since real life is a non-ideal situation it will actually be slightly higher, but we can disregard that.) That's the easy part and only applies to strong acids. For other (weak) acids of formula HA ⇌ H+ + A-, the pH is dependent upon the acid dissociation constant pKa, in which case pH = pKa + log([A-]/[HA]). Say you have a weak acid with a pKa of 2.0 and a molarity of .01 M. Since pKa = -log(Ka), that means that Ka = .01. The definition of Ka is [A-][H+]/[HA]. Let's call [A-] and [H+] x for this purpose; this makes [HA] = .01 - x; thus, .01 = x2/(.01 - x). Solving for x gives x2 + .01x - .0001 = 0; using the quadratic formula we get .00618 M. Now we may derive the pH. pH = pKa + log([A-]/[HA]) = 2 + log(.00618/.00382) = 2.21.
What is the function of Polyacrylic Acid--PAA?
Polyacrylic Acid (PAA) 【CAS】 9003-01-4 Properties:PAA is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

What is the .01 percent not killed by Lysol?
The 0.01% that Lysol does not kill may include certain viruses or bacteria that are resistant to the active ingredients in Lysol. It is important to follow the manufacturer's instructions for proper use of the product to ensure maximum effectiveness in killing harmful germs.
How much bleach in 20 gallon water to make 1 percent solution?
A one percent solution means 1 part beach and 99 parts water. So we can answer the question by solving the equation 1 part bleach/99 parts water=x gallons bleach/20 gallons water. You can cross multiply. This is the same as 99x=20 so x=20/99 or .20 Let's check .20 gallons bleach/ 20 gallons water=.01 which is 1% .2 gallons is the same as 3.2 cups or 25.6 fluid oz.
