If I have 100,000 litres of water at a pH of 8. How much NH3 at a concentration of 25%, pH >13 would I require to bring total pH to 9 or greater. An approximate figure would suffice if anyone can help.

Thanks in advance.

We need to know what is in the water and its concentration that is keeping the pH at 8. Is it buffered at pH 8, for example?

Thanks for the reply.

It's just a reservoir of storm water. The pH before hand might have been 7 or 7.5, I'm just wondering how much ammonia it would take to raise the pH of 100,000 litres by 1. Either from 7 - 8 or 7.5 - 8.5 Hopefully this is enough information but if you require more I'll do my best and thanks again.
