I'm a chemist waste water operator and we use caustic soda to raise pH levels and sulfuric acid to lower pH levels
Yes, caustic substances are commonly used to raise the pH levels in water. One such substance is sodium hydroxide, which can increase pH levels by releasing hydroxide ions that react with acidic components in the water. However, it is important to handle caustic substances with care and follow proper dosing guidelines to avoid overalkalizing the water.
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
Adding calcium hydroxide to water would raise the pH of the solution. Calcium hydroxide is a strong base and will dissociate in water to increase the concentration of hydroxide ions, leading to an increase in pH.
10 BE Caustic typically contains around 54-65% water.
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
No you add acid to lower the pH

Adding salt to water will lower the freezing point and raise the boiling point of the water, but it will not directly affect the temperature at which the water is heated or cooled.

No, salt does not lower the boiling temperature of water. In fact, adding salt to water increases its boiling point. This occurs because the salt disrupts the formation of hydrogen bonds between water molecules, making it harder for them to escape as vapor.
To eliminate the problem of caustic embrittlement use sodium phosphate instead of sodium carbonate as softening reagents. Adding tannin or lignin to boiler water blocks the hair-line cracks and prevents infiltration of NaOH into these areas. Adding Na2SO4 to boiler water also blocks the hair-line cracks.
