Work Problem: Calculation of Molar Mass of Unknown Base Using Titration With a Strong Acid

Given Question: A student titrates 2.0135 grams of an unknown monobase weak base to the equivalence point with 67.02 mL of .5003 M HCl(aq). What is the molar mass of the weak base?  Step 1: This is to sort out what we're given in the equation, as well as some previous knowledge. We'll use the first … Continue reading Work Problem: Calculation of Molar Mass of Unknown Base Using Titration With a Strong Acid

Interview with James Nowick- Researcher, Educator, Advocate.

HeychemTutor got a chance to sit down with esteemed professor and advocate Dr. James Nowick, who is currently based out of the University of California-Irvine. We sat down to discuss chemistry, LGBTQIA+ rights, and advocacy. This was a project Heychem set in celebration of June 2017 Pride month. Contact us with questions, concerns, or complications … Continue reading Interview with James Nowick- Researcher, Educator, Advocate.

Determining the Molar Solubility of Iron (II) Hydroxide

Given Question: Calculate the molar solubility of Fe(OH)2 (Ksp=4.87*10^-7).  Tutor's Note: The Ksp radical that's written down comes in later, I got confuzzled by my own notes! Happens to all of us. Sorry students 🙂  Step 1: Write out the reaction equation with all ions. Make sure it's balanced! We'll use this in the next step with … Continue reading Determining the Molar Solubility of Iron (II) Hydroxide
