Only if it is the same acid.

ie. You can have 1.0moldm^-3 H2SO4 (sulfuric acid, in car batteries) and 1.0moldm^-3 HCO3 (carbonic acid, in natural acid rain). Even though they are the same concentration, the sulfuric acid is much stronger.

The pH value gives you the concentration of an acid or more precisely the concentration of the protons that are solved in the water.

You can easily calculate the concentration from the pH with the formula:

c(H+) = 10-pH

So in your case pH 5 contains 10-5 = 0,00001 mol/L,

pH 2 contains 10-2 = 0,01 mol/L

- so you have 1000 times the concentration of acid in the form of H+

What is a solution that contains an excess of protons?

The solution is an acid. If it is in water (supposedly meant by questioneer), the pH value is below 7.0, so it is an acid solution: more H+ than OH-.


What makes some acids like vinegar weaker than other acids such as sulfuric acid?

They do not disassociate more than about 1% in solution while sulfuric acid does disassociate almost 100% in solution. Just the large variance in proton donation in solution marks a weak acid from a strong acid.


Would magnesium react more vigorously with hydrochloric acid than vinegar?

Indeed it would. Hydrochloric acid is a strong acid which means it disassociates almost 100% in solution ( donates almost all of it's H + ) while acetic acid is a weak organic acid that may not disassociate more than 1% in solution.


How acidic is hydrochloric acid?

Hydrochloric acid is a strong acid, which means it dissociates completely in solution. You can not be more ' acidic ' than that. Just because an acid ionizes completely doesn't really say how acidic a solution of HCl will be. HCl is defined as a strong acid because it ionizes completely. However, if its diluted enough one can drink it just like vinegar (about a 5% solution of acetic acid). Of course one could dilute it enough to make it so the solution is pretty much no more acidic than pure water. The original answer was probably answering what was the intent of the question, whether HCl is a strong or weak acid.


Why is a acid called a acid?

They are acidic due to hydrogen ions. The more hydrogen ions converted from the original solution there are the more acidic it will be. For example Hydrochloric Acid converts more hydrogen ions from (hydrogen + water + chloride) solution than citric acid does from its respective solution...

Why is vinegar weaker than sulfuric acid?

Because the acid in vinegar is acetic acid, a weak organic acid that disassociates in solution only to about 1%. Sulfuric acid disassociates almost 100% in solution, so the proton concentration, H3O +, is much more concentrated in a strong acid than in a weak one.

What acid is a solution with more what?

H+ than OH- (more hydrogen ions than hydroxide ions). This is what makes acid, acid, and not water, or base, or anything else.


How much pure acid should be mixed with 2 gallons of a 50 percent acid solution in order to get an 80 percent acid solution?

pH less than 7


What is the difference between a concentration and a dilute?

A concentrated acid has more acid than water and a dilute acid has more water than acid. True facts, otherwise known as its molarity. The greater the molarity the more concentrated it is (moles of acid/ liter of solution)


Why is ethanoic acid a stronger acid in liquid ammonia than in aqueous solution?

Liquid ammonia is a more polar solvent than water

Is it possible to mix a 10 percent acid solution and a 40 percent acid solution to obtain a 60 percent acid solution?

No. The reulting concentration (percent) must be between the two components. So, with the two acids you are mixing, you cannot get an acid that is less than 10% or more than 40%
