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.

How is potassium hydroxide different from dilute nitric acid?
Potassium hydroxide is a strong base, while dilute nitric acid is a strong acid. Potassium hydroxide is alkaline, whereas dilute nitric acid is acidic. They have different chemical properties and uses in various processes.
Is 4.5-5.2 a strong base range for pH?
pH is measured on a 0-14 scale. When something has a pH of 0-7 it is considered an acid. When it is from 7-14 it is a base. Therefore, something falling within the range of 4.5-5.2 is a weak acid and not a base.
What is the pH number for dilute hydrochloric acid?
Dilute hydrochloric acid typically has a pH around 1 to 2.
Is dilute hydrochloric acid a strong acid or a weak acid I need this by today thanks?
It is actually classed as a strong acid being fully ionized
What is the pH value of dilute hydrochloric acid?
This depends on concentration AND typeExample: pH = 1.0 for 0.10 mol/L acids which are strong and monoprotic (like HCl and HNO3)0.10 mol/L Acetic acid (weak, pKa=4.77) pH will be about 2.4 (in stead of 1.0 , if it were strong)

What is the pH range of and acid?
The pH range of an acid is typically below 7 on the pH scale. Strong acids have a pH closer to 0, while weak acids have a pH closer to 7.
What pH level is Hydrochloric acid?
pH depends on the concentration of the acid as well as how strong it is. A 1.0M solution ( a measure of the number of molecules per liter) has a pH of 0 but a more dilute solution will have a higher (less acidic pH).
What is the hydrochloric acid pH scale?
HCl is a very strong acid: dilute solution (eg. 3.65 g/L) has pH of 1.0 , or when concentration is 3.65 mg/L then pH = 4.0.
What is diloute acid?
Dilute acid is a solution of acid in water with a lower concentration of acid. It is commonly used in various chemical reactions and experiments where a less concentrated acid solution is needed to prevent strong reactions or harm. Dilute acid solutions have a lower pH compared to concentrated acid solutions.
What is the pH value of dilute acetic acid?
The pH of dilute acetic acid solution is around 2.4. This is because acetic acid is a weak acid that partially dissociates in water, resulting in the release of hydrogen ions which lower the pH of the solution.
PH is 3 Is the solution a very dilute solution of a weak acid or a more concentrated solution of a strong acid Propose a way to answer the question?
A pH of 3 indicates that the solution is acidic. To determine if it is a very dilute solution of a weak acid or a more concentrated solution of a strong acid, you could perform a titration experiment to measure the exact concentration of the acid present. This would involve adding a base of known concentration to the solution until it reaches a neutral pH, allowing you to calculate the initial acid concentration.
How can you make a weak acid?
if you have an acid that is water soluble, you can dilute it with water. basically just add a base until it is the pH you want. Dilute a stronger acid in water or nonreactive base, citric acids in fruit like oranges are acids in themselves and are considered a weaker acid. Josh_af
