Yes, if the concentration of hydrogen ions is above 1 M, then pH will be negative. An example is Sulfuric acid, which can get a proton concentration up to 18 M which would be a pH of -1.3.
pH 0-14
take the negative logarithm ex. 10^-4 has a pH of 4
A negative plus a negative still gives a negative answer.
The negative logarithm of the molar concentration of hydronium (H3O+) ions. pH=-log[H3O+]
because they don't have enough acid in it.
pH is a pure number. It doesn't have units. It is the negative log of the hydrogen ion concentration.
The pH of a solution can be less than zero. Remember that pH is defined as the negative logarithm of the hydronium ion concentration, pH = -log[H3O+]. For pH to be negative, the log of the hydronium ion concentration needs to be positive. The log of a number is only positive if that number is greater than one. For example, the value of log(2) is about 0.30. This means that the pH of a strong acid that has a concentration of greater than 1 molar will be negative.
Well...zero isn't really the lowest number on the pH scale. To simplify things, we teach kids that the scale goes from 0-14, but in reality, a solution can have a negative pH. The pH is the negative log of the hydrogen concentration or -log[H+]. So for -log[H+] to be negative, log[H+] has to be positive; therefore, [H+] would have to be greater than one. A solution that has a negative pH is extremely acidic! For example, a solution with a hydrogen concentration of 2.2 M would have a pH of -log[2.2] = -0.342 The reason we use 0-14 in abstraction is because pH + pOH = 14
pH is the Negative power of H+ ions so "neutral" is ten to the minus 7th power (or pH=7) so acid is a Lower number and alkaline is a Higher number.
Yes. An acid will have a negative PH under the circumstance that it is a strong acid as well as it has a concentration of over 1 mol/L as using the function -log(H3O+)... If a number above 1 is entered, it will yield a negative number.
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
Hydrogen ion concentration increases.
The pH is the negative log of [H+].
Iron does not have a pH on its own. pH is the negative log concentration of H+. Iron can be affected by pH though.
hydrogen
It is the negative value of the 10-base logarithmof [positive real number](cf. mathematics)
pH is the negative logarithm of the hydrogen ion activity in a solution.
