How many numbers are on the pH scale?
10
What is the scale you use to measure acids and bases and what is the range of number?
the scale used to measure acid and bases is called a pH scale. the numbers range from 1-14 and go as following- to show an acid= 1-6 nuetral= 7 to show a base= 8-14
How do you Calculate the hardness of a water sample?
u can chek the hardness by pH scale...lolz
What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
PH is it a quantitative or qualitative?
PH is a number, so it is quantitative.
What number is highest on the pH scale?
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
Is the base the highest number on a pH scale?
Yes. A base has a pH of greater than 7. An acid has a pH of less than 7.
Can the lowest acid on to pH scale kill you?
Definately
Which acid is the lowest number on the pH scale?
The pH scale does not have an easily defined lowest number. Often, answers of 1 or 0 are given, but not correct. The pH actually goes below zero, so that negative values are possible. In order to measure a pH there must be some water present, so the theoretical lowest pH value would be slightly less than -1.
Is 6 a natural number?
The number 6 is not a natural number on the pH scale if that is what you mean. In fact the number 7 is a natural and neutral number on the pH scale ( on the pH scale number 7 is a green colour.)
What is the highest pH level for a base?
pH can exceed 0 and 14 infinitely. Which means it can be any number from negative infinity to positive infinity (tho it does not exist in real life). So there is no so called highest/lowest pH level.
What number is smelling slats on the PH scale?
Any smelling on the pH scale.
What number does the pH scale end?
The range of the pH scale is 0-14.
What is the neutral number in the pH scale?
7 is neutral on the pH scale.
What does the number seven mean on a pH scale?
it is neutral. Water is a 7 on the pH scale
Place the following substances in order of pH from lowest pH to highest?
acids, neutral compounds, bases
Why is zero the lowest number on the pH scale?
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
