The pH of chlorine is 12.5

Chlorine is made to be pH neutral (7.0) for pools. If you are looking for a base (due to high pH) try "Soda Ash" or a product that claims pH down, results.

The most important variable, that is also the most misunderstood, is pH (Hydrogen Potential/Power). What actually is pH? The scientific definition is the logarithm of the reciprocal of the hydrogen ion concentration. Or more simply stated pH is a number between 0 and 14, denoting various degrees of acidity or alkalinity. Neutral water has a pH of 7. Water below 7 is acidic and becomes more acidic as it approached zero. Water above 7 is alkaline and alkalinity increases as it approaches 14. What is the pH of your water and how does it improve or impair the chlorine's ability to be effective? When the pH of your water is 7 or below, chlorine will act primarily as a sanitizer. At this level, it is very effect at killing bacteria. At 7.4, chlorine will act equally as a sanitizer and oxidizer. Above 7.8, the chlorine will act principally as an oxidizer. The pH of chlorine is 11.7. It would seem logical that adding chlorine into water having a neutral pH would make the water more alkaline and this is true in a majority of the cases. Keeping this in mind, it may be necessary to lower the pH of water with an acid in order to increase the efficacy of chlorine in the killing of bacteria if your water has a high pH to begin with. When chlorine is added to water it becomes hypochlorite ions (OCI) and hypochlorous acid (HOCI) in a quantity determined by the pH as indicated by the chart below: pH OCI HOCI 6.0 3.50% 96.50% 6.5 10.00% 90.00% 7.0 27.50% 72.50% 7.5 50.00% 50.00% 8.0 78.50% 21.50% 8.5 90.00% 10.00%
Depends on the type of chlorine you are using as each type of chlorine product has it's own pH level. i.e Liquid chlorine (sodium hypochlorite) has a natural pH of about 14. Trichlo products have a pH of about 3 Dichlor products have a pH of about 6.8 Gas Chlorine has a pH of <1 So based on the above lets say you are using liquid chlorine in a concrete pool, the pH will tend to be high (alkaline) due to the high pH of the chlorine product coupled with the fact the pool is concrete.
Adjusting the chlorine content will almost certainly affect the pH, so it would be simpler to get the chlorine level correct first and then titrate to the proper pH.
yes, and the pH can go up significantly depending on what type of chlorine used for shocking. Liquid chlorine (sodium hypochlorite) will cause the PH to increase at a higher rate than that of granular chlorine (such as calcium hypochlorite)
Do you have a chlorine generator? No.

Add sodium bicarb to raise pH. Chlorine will go down by itself or add sodium thiosulfate
Since most types of chlorine are very high in PH it may effect the over all PH of the water if it is not buffered.
Chlorinated water is basic: pH = 7-8.
