You think probable to standard pH solutions and buffer solutions.
First, identify the indicators used in the experiment. Then, prepare a set of solutions with known colors at different pH levels. Finally, compare the color change of the indicators with the color changes in the solutions to determine the pH of the solution being tested.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
The pH scale is used to classify the strength of acid or basic solutions. On the pH scale, solutions with a pH less than 7 are considered acidic, solutions with a pH of 7 are neutral, and solutions with a pH greater than 7 are basic.
Alkaline solutions have a pH higher than 7
Phenolphthalein is a pH indicator that turns pink in basic solutions, and colorless in acidic solutions. Normal pH of saliva ranges between 6.2 (acidic) and 7.4 (basic), with 7 being neutral pH. So, the answer is, "it depends." Is the saliva acidic, or basic?

Alkaline solutions have a pH higher than 7
Acids solutions have a pH under 7; basic solutions have a pH over 7.

solutions with a pH less than seven are acids. solutions with a pH greater than seven are basic. if a solution has a pH exactly equal to seven it is neutral. there are many more also i just gave you 3 of the answers.
The pH of solutions (liquids) is measured.
Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are alkaline.
in neutral solutions ph paper turns to blue!
Basic solutions have a higher concentration of hydroxide ions (OH-) compared to acidic solutions. This property allows basic solutions to have a pH greater than 7, while acidic solutions have a pH less than 7.
Acidic solutions have a pH under 7.A neutral solution has a pH of 7.Basic solutions have a pH over 7.
