The scale used to classify the strength of acid or basic solutions?
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.
Why are buffering solutions used?
to maintain the pH
The scale used to classify the strength of acid and basic solutions?
The pH scale.
What is propanol?
It is an alkanolamine, used to neutralise the pH in cosmetic solutions/suspensions.
Alkaline solutions have pH values below 7?
Alkaline solutions have a pH higher than 7
Why can't a litmus indicator be used to distinguish between solutions pH 2?
A litmus indicator cannot distinguish between solutions with the same pH, such as two solutions both at pH 2, because it only indicates whether a solution is acidic or basic, not the specific pH value. Since both solutions at pH 2 will turn litmus paper red, the indicator will not provide any additional information to differentiate between them. To differentiate between solutions with the same pH, more precise pH indicators or pH meters would be needed.
What cannot use for find pH of solution 1.ph paper 2.litmus paper?
pH papers are used to find pH of solutions, not litmus paper.
How is acid and base and pH connected?
Acids solutions have a pH under 7; basic solutions have a pH over 7.
What makes up PH scale?
The Ph scale doesn't have units it's a model to show where solutions rank based on the -Log of the concentration of H+ ions
Which indicator would be the best to show a change from an acid to a base?
A pH indicator like litmus paper can best show a change from an acid to a base. Litmus paper is red in acidic solutions and blue in basic solutions, making it easy to visually detect the shift in pH.
What mixes many solutions to compare pH?
A pH meter can mix multiple solutions by taking small samples and measuring the pH of each. Alternatively, a pH indicator solution can be added to each solution to visually compare the color changes and identify differences in pH levels. Another option is to create a standard curve using known pH buffer solutions to compare against the solutions being tested.
What scale of zero to 14?
The scale of zero to 14 is typically used to measure pH levels, with zero representing highly acidic solutions, seven representing neutral solutions, and 14 representing highly basic solutions.
