Phenolphthalein is colorless in acidic solutions with a pH below 8, and turns pink in basic solutions with a pH above 8. In solutions with pH values ranging from 2 to 6, phenolphthalein would remain colorless.
These solutions are basic and can neutralize acids.
Acidic solutions have a pH under 7.
A solution with a pH above 7 is considered basic or alkaline. In basic solutions, there are more hydroxide ions (OH-) than hydrogen ions (H+). Examples of basic solutions include soaps, household ammonia, and bleach.
The normal arterial pH range is 7.35 to 7.45. Values below this range indicate acidosis, while values above indicate alkalosis. Maintaining pH within this range is crucial for proper physiological function.
The possible range of pH for an acid would be anything lower than 7 and above zero.
Alkaline solutions have a pH higher than 7
The pH range of an alkali solution is typically greater than 7, indicating that it is basic or alkaline. Alkali solutions have pH values above 7, with stronger alkalis having higher pH values.
Phenolphthalein is colorless in acidic solutions with a pH below 8, and turns pink in basic solutions with a pH above 8. In solutions with pH values ranging from 2 to 6, phenolphthalein would remain colorless.
The higher the pH value the higher the Alkaline concentration.
The range of pH values is 0 - 14.
it is a substance called alkaline that is indicated by alkalines s
These solutions are basic and can neutralize acids.
A pH value below 7 indicates that a solution is acidic. The lower the pH value, the more acidic the solution is. Typically, acidic solutions have a pH between 0 and 6.9.
No, a negative pH value is not possible in a solution. pH values range from 0 to 14, with 7 being neutral. Solutions with a pH below 7 are acidic, while those above 7 are basic.
do you mean the full pH range? the pH range varies from 1-14 with 1 being the most acidic, 7 neutral, and 14 the most alkaline
A base typically has a pH range of 8 to 14. pH values above 7 indicate alkalinity, with higher values indicating stronger bases.
