In acidic medium, the equivalence point can be detected using an acid-base indicator that undergoes a color change at the pH corresponding to the equivalence point. Alternatively, a pH meter can be used to monitor the pH of the solution during the titration, with the equivalence point identified as the point of maximum change in pH.
If you omitted methyl red in the reaction mixture, you would not be able to visually monitor or detect the pH change in the reaction. Methyl red is a pH indicator that changes color in response to pH changes, so without it, you would not be able to accurately determine when the reaction has reached a specific pH endpoint.
By testing the pH level using pH-testing paper, then comparing the normal balance against that of the stripe you can detect baking soda. The problem it tells which alkalizing agent is in the food.
pH can be measured using a pH meter, pH paper, or pH indicator solutions. These tools detect the acidity or basicity of a solution by measuring the concentration of hydrogen ions present.
The pH of human blood tends to be very stable because the dissolved carbon dioxide, which is a metabolic by-product, forms carbonic acid which acts as a pH buffer. Smoking tobacco will add more carbon dioxide (as well as carbon monoxide) to the blood, but the pH will remain the same.

Scientists monitor pH values of rivers and lakes to assess water quality and determine if it is suitable for supporting aquatic life. Changes in pH can indicate pollution from sources like acid rain or agricultural runoff, and can have harmful effects on the ecosystem. Monitoring pH helps to track these changes and take necessary actions to protect the environment.
Chemoreceptors are sensory receptors that can detect changes in hydrogen ion concentrations. These receptors are particularly sensitive to changes in pH levels in the body, helping to regulate processes such as breathing and maintaining blood pH balance.
To test the pH of the saliva and the guess the pH of the entire body is not a logical concept. You better take the blood sample and get the pH tested for the same. It is very accurate method to detect the pH of the body. The pH of the saliva may get acidic due to starchy food you have eaten before the examination of the saliva.
You can raise the pH of the soil by adding lime or other soil amendments that increase pH. Test the soil again after amending to ensure that the pH is around 6. Make sure to monitor the pH periodically to maintain the desired level for optimal plant growth.
Chemical indicators that detect carbon dioxide include bromothymol blue, phenol red, and pH-sensitive dyes like universal indicator. These indicators change color in the presence of carbon dioxide due to a change in pH levels.
You can adjust the pH of an ammonium acetate solution by adding a strong acid (such as hydrochloric acid) to lower the pH or a strong base (such as sodium hydroxide) to raise the pH. Use a pH meter to monitor the pH levels during the adjustment process until you reach the desired pH value.
