An indicator is what type of compound?
a. reducing agent
b. oxidizing agent
c. weak base or acid
d. strong base or acid
To determine the type of compound an indicator is, we need to first understand what an indicator is.
An indicator is a substance that undergoes a noticeable visual change, such as a color change, to indicate the pH (acidity or basicity) of a solution. It is commonly used in laboratories, medical tests, and various chemical processes.
Now, let's analyze the options provided:
a. Reducing agent: A reducing agent is a substance that donates electrons, resulting in the reduction of another substance. Indicators are not typically reducing agents.
b. Oxidizing agent: An oxidizing agent is a substance that accepts electrons, leading to the oxidation of another substance. Indicators are not generally classified as oxidizing agents.
c. Weak base or acid: Weak bases or acids are substances that release or accept small amounts of hydrogen ions (H+) in a solution, resulting in a slight change in pH. Indicators can indeed be weak bases or weak acids that exhibit color changes at specific pH ranges.
d. Strong base or acid: Strong bases or acids are substances that release or accept a significant amount of hydrogen ions (H+) in a solution, leading to a more pronounced change in pH. Indicators are typically not strong bases or acids.
Based on the explanations above, the correct answer is option c. Indicators are often weak bases or acids that show changes in color corresponding to different pH levels.
Poor question for it has 3 answers and another type is not listed..
Usually c (for acid/base titrations) but sometimes a or b. And the Mohr titration depends upon the Ksp of Ag2CrO4 which is none of the aboe.
