The last edit to this post was made by Zaihui Kangqiao on 2016-10-18 at 14:35. The Chemical Engineering Theory section is now launching a \"One Question per Day\" initiative aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope for your active support~~~ Answers to the questions in the \"One Question per Day\" initiative can be viewed directly; the thread will be closed after 1 day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What should be the pH value after adding chemicals to the cooling water?
The latest standards set by the Ministry of Electricity are 8.0–9.0, with a conductivity of 0.4–2.0 us/cm and copper ions at 20 ppb.
What should the pH value be after adding chemicals to the internal cooling water? ≥6.8
