【Daily Question】Chemical Engineering Principles 508: Alkalinity (January 17)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering\" will be introduced. We hope for your active support! Wishing you a happy Christmas! Replies to the \"One Question per Day\" campaign can be viewed directly at **; the topic will be closed after 1 day! ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ True or False: Alkalinity is an important indicator of polyaluminum. When the alkalinity is below 30%, the coagulation effect is better. Wrong
Error: When the alkalinity is below 30%, the solution is unstable and the flocculation effect is poor
