What range of pH values corresponds to acid solution?
The possible range of pH for an acid would be anything lower than 7 and above zero.
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.
What property of phenolphthalein makes it useful indicator for acid-base titrations having equivalence points in the pH range from 7-9?
Phenolphthalein changes color in the pH range of 8.2-10, which makes it suitable for acid-base titrations with equivalence points in the pH range of 7-9. It remains colorless in acidic solutions and turns pink in basic solutions, providing a clear visual indication of the endpoint of the titration within the desired pH range.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
Oxalic acid is a weak acid and phenolphthalein is a pH indicator that changes color in the pH range of 8.2 to 10. Oxalic acid solutions typically have a pH below the range where phenolphthalein changes color, so there is no visible change when phenolphthalein is added to oxalic acid.
Which of the unknown colorless solutions are acidic?
To determine if a colorless solution is acidic, you can test its pH using a pH indicator strip or a pH meter. If the pH is below 7, the solution is acidic. Common acidic solutions include hydrochloric acid, sulfuric acid, and acetic acid.
What number range can you find an acid-in on the pH scale?
Acidic solutions have a pH under 7.
What range of pH values corresponds to acid solution?
The possible range of pH for an acid would be anything lower than 7 and above zero.
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.
A acid of pH below?
Solutions with pH below 7 are called acidic or 'acid'
Does acid solutions have a pH above 7?
yes all acids have pH below 7 as SUSTANCES HAVING Ph below 7 are acids and that having pH up 7 are bases
How is acid and base and pH connected?
Acids solutions have a pH under 7; basic solutions have a pH over 7.
What is the pH score for a strong acid and a strong base?
A strong acid will have a low pH and a strong base will have a high pH.

Are glass pH electrodes compatible with muriatic acid or solutions?
Glass pH electrodes are generally not recommended for use with muriatic acid or solutions with low pH as they can deteriorate and lead to inaccurate readings. It is best to use a specialized electrode such as a combination or ISFET pH electrode that is designed for measuring low pH solutions.
Which of the unknown colorless solutions are acidic?
To determine if a colorless solution is acidic, you can test its pH using a pH indicator strip or a pH meter. If the pH is below 7, the solution is acidic. Common acidic solutions include hydrochloric acid, sulfuric acid, and acetic acid.
What is pH of an acid?
The range of an acid is to 1 to 6........
