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.
Potassium hydroxide is a powerful base with a pH of 14. Dilute nitric acid is a strong acid with a pH of between 0-1 usually.
1 is strong acid 7 is neutral 14 is strong alkaline
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).
the solution is a very strong acidic solution because the closer to 0 the pH value is the stronger the pH of the solution/substance.
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)

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.

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.
It's considered a dilute acid, not a weak acid. That term has a very specific meaning. A strong acid is one that ionizes (many chemistry texts use the word "dissociate") completely in water, and a weak acid is one that doesn't completely ionize. Hydrochloric acid is a "strong" acid; hydrofluoric acid is a "weak" acid even though it's more corrosive than hydrochloric acid is. So...you could take hydrochloric acid (a strong acid) and mix it with a lot of water, get it up to pH 6, and still have a strong acid.

No. A pH in the range of 11 to 14 would be a strong or concentrated base. An acid has a pH less than 7.
Acids can range from 6.9 to 0 on the pH scale, with a solution with a pH of 6.9 being extremely weak, and a solution with a pH of 0 being as strong as 1.0 mol/l [H3O+].Added:(For even higher concentration the pH value can be negative, eg. 2.0 M strong acid has pH = - 0.3)
Bases run from 7.1 to 14 on the ph scale. A strong base would be in the 12-14 range. A 3ph is a relatively strong acid.
