What is a pH scale How do you make a pH scale pls answer FAST?
its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
Is ketchup an acid or alkali?
Vinegar is an acid. It is between 2 and 3 on the pH scale.
Are weak acids on the pH scale less than 3?
NO!!!! The pH scale is from 0 to 14. The lower the numerical value of the pH , then the stronger the acid. e.g. pH = 1 Strongly acidic ( e.g. Hydrochloric Acid). pH = 4 Weakly acidic ( e.g. Ethanoic (Acetic) acid). pH = 7 Neutrality (Water) pH = 9 Weakly Alkaline ( Ammonia Solution). pH = 12 Strongly Alkaline ( Sodium Hydroxide). pH = 14 Very strongly alkaline ( very weakly acidic ; in extremis). NB The pH is the 'negative logarithm , to the base 10, of the hydrogen ion conc'n. Algebraically ; pH = -(log(10)[H^(+)]) The inverse maths. function is [H^(+)] = 10^(-pH). So if you have a pH = 1 Then H^(+) = 10^(-1) = 0.1 ( Casually a tenth of the sol'n is hydrogen ions). If you have a pH = 12 Then H^(+) = 10^(-12) = 0.000000000001 (Casually a trillionth of the solution is hydrogen ions; usually considered as strongly alkaline with a pOH = 0.01, an hundredth of the solution is hydroxide ions, compared to a trillionth( an extremely tiny amount), of hydrogen ions.
How does a pH of 3 differ from pH of 4 Which one is stronger or weaker Why?
A pH of 3 is more acidic than a pH of 4, meaning that a solution with a pH of 3 has ten times more hydrogen ions (H⁺) than one with a pH of 4. The pH scale is logarithmic, so each whole number change represents a tenfold difference in acidity. Therefore, a pH of 3 indicates a stronger acid, while a pH of 4 is a weaker acid.
Is lemon juice above 7 or below 7 on the pH scale?
Lemon juice is below 7 on the pH scale, typically around 2 to 3. This makes it acidic.
Is weak base on the pH scale is it 3?
any thing with a pH below 7 is an acid and anything with a pH above 7 is a base. So a weak base would be around 8
What is the pH difference between a strong acid and a weak acid n the pH scale?
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
Is weak acid on the pH scale is it 3?
A acid is 6 or less A Base is more than 8 7 is neither So is it is
Is strong acid on the pH scale is it 3?
Acids are numbered from 1 to 6.9. The closer the number is to one, the stronger an acid it is. A 6ph would be a weak acid.
What is the pH level for acetic acid?
The pH level for acetic acid is 3... The pH level for acetic acid is 3...
Is alkali an acid?
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
Is strong acid on the pH scale is 3?
Yes, a strong acid on the pH scale with a pH of 3 is considered highly acidic. The pH scale ranges from 0 to 14, with lower numbers indicating stronger acidity. Strong acids have pH values closer to 0.
A weak acid has a pH of?
A weak acid typically has a pH between 3 and 6. This is due to the partial dissociation of the weak acid molecules in water, resulting in a lower concentration of hydronium ions and a slightly acidic pH.

Which has a lower pH weak acids or strong acids?
pH = 0 to 2 is a STRONG acid. ( e.g. Hydrochloric Acid) pH = 3 to 6 is a WEAK acid. ( e.g. Ethanoic (Acetic) acid). NB THe greater the numerical value of the pH , then the weaker the acid.
What would be the pH of a weak acid?
3/4-6
Citric acid has a pH between 1 and 3 It is considered to be a?
strong acid
