The pH range of drinking water is typically between 6.5 and 8.5.
The pH range of drinking water is important for ensuring its safety and taste.
The pH scale ranges from 0 to 14, with 7 being neutral.
Drinking water with a pH below 6.5 may be acidic and potentially harmful.
Drinking water with a pH above 8.5 may be alkaline and have a bitter taste.
Maintaining a pH range of 6.5 to 8.5 is recommended for drinking water.
There are several types of titration methods used in analytical chemistry to determine the concentration of a substance.
Acid-base titration: involves the reaction between an acid and a base to determine the concentration of either
Redox titration: involves the transfer of electrons between reactants to determine the concentration of a substance
Complexometric titration: involves the formation of a complex between a metal...
I was interviewed before Jul 2016.
To increase TDS in a boiler, you can add chemicals or increase the concentration of the feedwater.
Add chemicals such as sodium phosphate or sodium hydroxide to increase TDS.
Increase the concentration of the feedwater by reducing the amount of condensate return or increasing the makeup water.
Regularly monitor and adjust the TDS levels to maintain optimal boiler performance.
