I need some help calculating basic chemistry. I need to know how much ammonia I need to add to a volume of water to reach the appropriate pH level.(adsbygoogle = window.adsbygoogle || []).push({});

I have 50 cubic meters of demin water that I need to raise to a pH of 11. Volume is not flowing.

I am using aqueous ammonia of 25% solution. I was able to find online that a pH of 11 is equal to 50 mg/L (not 100% sure).

This a two part question:

How do I calculate the concentration of the solution based on the pH?

How do I calculate the required volume to dose the 50 cubic meters to reach the pH of 11?

Also, does anyone have a pH vs mg/L (ppm) in a quick reference chart?

After some research I found some answers and it calculated (roughly) that I need 15 liters.

Thanks,
