If the pH scale shows a colour between red and light green, then it is acidic.
When the colour is light green, then it is neutral.
When it shows colour between light green and dark blue, then it is basic.
For numerical values:-
0-7:- Acidic
7:- Neutral
7-14:- basic

∙ 12y agopH is the negative logarithm of the activity of the cation H+ in a solution.
A pH=7 is neutral; under 7 the pH is acidic, above 7 the pH is alkaline.

∙ 13y agopH = - log [h3o+]
The pH is equal to the negative log of the concentration of hydronium ions. The concentration of h+ is equivalent.

What is the PH values indicate a slightly acidic solution?
7 is neutral, and below 7 is acidic, for example 6.5
Does it make sense that disinfectant is acidic?
Yes. It makes sense that disinfectants are slightly acidic (pH3 -5). Bacteria and fungi are more susceptible to being killed at slightly acidic pH values. Fungi in particular are harder to kill so pH is particularly important.
What range of pH values indicates a solution is alkaline?
it is a substance called alkaline that is indicated by alkalines s
A solution that is a 4 on the pH scale is what?
A solution with a pH of 4 is considered acidic. It has a higher concentration of hydrogen ions (H+) compared to a neutral solution with a pH of 7. Solutions with pH values below 7 are progressively more acidic, while those above 7 are progressively more basic.
What number on the pH scale indicates the strongest acid solution?
The pH scale does not indicate the strength of the acid, so there is no number on the pH scale that indicates the strongest acid. A pH value of zero will be the most concentrated strong acid, but even that isn't exactly correct. Concentrations greater than 1 M have pH values <0, but are not useful values because of intermolecular interactions and activity values.
P.H values indicate a slightly acidic solution?
6.5
What is the PH values indicate a slightly acidic solution?
7 is neutral, and below 7 is acidic, for example 6.5
What pH ranges is a strong base 1ph13 20 ph45 52 ph71 90 or pH 112 120?
The values given are not correct for pH. But the answer is as follows:pH will range from 0 to 14.A pH of 7 indicates neutral solution; pH below 7 for acidic solution and pH above 7 indicates basic solution.pH of 14 will be the most basic.pH values cannot be over 14 as given in the question.

How do the concentrations of hydrogen ion and hydroxide ion determine whether a solution is acidic basic or neutral?
A high concentration of hydrogen ion indicates that the solution is acidic, while a high concentration of hydroxide ion makes the solution basic. When the concentration of hydroxide ion is equal to hydrogen ion the solution is basic.
What range of pH values indicates a solution is alkaline?
it is a substance called alkaline that is indicated by alkalines s
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

A solution with a pH above 7 is?
A pH level of 7 is neutral. Acidic solutions have pH values less than 7. Basic solutions have pH values higher than 7......so your answer is... it is a BASE
How do you know a drug is acidic or basic from pka value?
To be honest, sometimes it can be extremely difficult to choose which equation you should use depending on whether the solution is basic or acidic. But what I do know, is that when the pka is small then the solution is acidic, and when the pka is large then the solution is basic. "A weak acid has a pKa value in the approximate range −2 to 12 in water. Acids with a pKa value of less than about −2 are said to be strong acids. " this being said, its hard to distinguish whether a solution is acidic or basic since they both have such a wide range of pka values. but if you want just a general guideline then i would stick with the rule "high pka=basic, low pka=acidic
What caused compounds to have lower pH values that the other compounds?
Compounds which form in water solutions hydrogen ions are considered acidic, with a p H under 7,0 in solution.
