What else can I help you with?
Strong bases have pH values ranging from 11 to 14 true or false?
The answer is true.(:
What is true about bases on the pH scale?
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
What are true about the pH scale the scale ranges from 1 to 15 true or false?
False. The pH scale ranges from 0 to 14. A pH of 7 is neutral, with values below 7 being acidic and above 7 being alkaline.
What are the pH values of acids Bases?
Acids have pH values below 7.0. Bases have values above 7.0.
Does alkaline solutions have pH values below 7?
The higher the pH value the higher the Alkaline concentration.
Alkaline solutions have pH values below 7?
Alkaline solutions have a pH higher than 7
Is one method for detecting the endpoint of a titration involves using an idicator dye that changes color at different pH values true or false?
True. One method for detecting the endpoint of a titration is indeed using an indicator dye that changes color at different pH values. The color change of the indicator dye can be observed to determine when the reaction between the titrant and analyte is complete.
Which phrase is not true about strong bases A. are metal hydroxides B. have pH ranges from 1 to 7 C. dissociate in water D. conduct electricity well?
B. have pH ranges from 1 to 7. This is not true because strong bases typically have pH values above 7, not within the acidic pH range of 1 to 7.
Is a pH 11 considered to be acidic?
No, a pH of 11 is considered alkaline, not acidic. pH values below 7 are acidic, while pH values above 7 are alkaline.
How can Acids and Alkalis be identified using an PH scale?
The pH scale has values ranging from 0-14. A substance with pH between 0-6 is considered as an acid, one with pH 7 is considered neutral while substances with pH in range 8-14 are considered as bases.
Which of these statements is correct with respect to pH?
Some true statements regarding pH include, the pH scale indicates concentrations of hydrogen and hydroxyl ions in a solution. Anything above a pH level of 7.0 is basic, anything above a 7.0 is acidic, and a change in one pH unit denotes a ten-fold increase or decrease in hydroxyl ion concentration.
What is the range of pH?
The range of pH values is 0 - 14.
