If the water contain impurities the freezing point is lowered.
7.What effect does water pH have on the rusting of nails?
Sodium bicarbonate increases the pH of water.
Adding hydrogen chloride to water the pH decrease.
Decreasing the temperature of water the value of pH increase.
These molecules haven't an effect on pH.
Heating pure water the pH decrease.
Increasing the temperature will cause the pH to decrease.
When sodium bicarbonate is dissolved in water, it increases the pH of the water, making it more basic.
It becomes lees acidic. The ph value goes up.
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
When baking soda is dissolved in water, the pH level increases. This is because baking soda is a basic compound that raises the pH of the solution.
the pH level of salt added to water is 7.5-7.8... almost neutral!
