Potassium hydrogen phthalate, known as KHP (molar mass =204.22 g / mol), can be obtained in high purity and is used to determine the concentration of solutions of strong bases by the reaction HP^-(a q) OH^-(a q) ⟶H2 O(l) P^2-(a q) If a typical titration experiment begins with approximately 0.5 g of KHP and has a final volume of about 100 mL, what is an appropriate indicator to use? The p Ka for HP^- is 5.51 | Numerade

KOH, aka Potassium Hydroxide or Potash, is a powerful solvent & corrosove chemical. So why am i carrying it in my mushroom basket? Reagents are chemicals that can be applied to fungi as a test for ID help. Different mushrooms react (or don’t) to different reagents by changing color. KOH is the most commonly used, but we also use Lye (NaOH) and Iron Sulfate (FeSO4).
