10 Questions
What is the significance of pH in water chemistry?
The pH of water is a measure of its free acidity or alkalinity, and is important for supply and sanitary engineers.
How does acidity change as the pH drops from 7 to 0?
Acidity, represented by $H^+$ concentration, increases as pH drops from 7 to 0.
What is the formula for calculating pH?
The formula for calculating pH is $pH = -log_{10}(1/[H^+])$.
What is the pH of neutrality and what does it indicate?
The pH of neutrality is 7, indicating equal concentration of $H^+$ ions and $OH^-$ ions in pure water at 25°C.
How does alkalinity change as the pH rises from 7 to 14?
Alkalinity, represented by $OH^-$ concentration, increases as pH rises from 7 to 14.
What are the chief causes of alkalinity in water?
Bicarbonates, carbonates, and hydroxide of alkali metals
Which form of alkalinity is most predominant in natural underground water bodies?
Bicarbonate alkalinity
What equipment is required for the determination of alkalinity?
Breaker 250 ml, Conical flasks, Pipette, Burette and Burette stand, Measuring cylinder, thermometer, pH meter
How is alkalinity principally expressed?
Hydroxide alkalinity, carbonate alkalinity, and bicarbonate alkalinity
Which metals chiefly contribute to alkalinity in water?
Ca, Mg, K, and Na
