Part a. Dissolving 1 mol of Al(NO3)3 in water dissociates into 1 mol Al3+ and 3 mol NO3-by the reaction: Al(NO3)3(s) → Al3+(aq) + 3 NO3-(aq) Therefore: concentration of Al3+ … See more a. State the concentration, in moles per liter, of each ion in 1.0 mol Al(NO3)3. b. State the concentration, in moles per liter, of each ion in 0.20 mol K2CrO4. See more Part a. Concentration of Al3+ = 1.0 M Concentration of NO3-= 3.0 M Part b. Concentration of CrO42- = 0.20 M Concentration of K+= … See more WebMay 2, 2024 · How to Calculate pH and [H+] The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value.

WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. WebJun 21, 2014 · 1. The key is to get the concentration of bromide ions and use that value in the Solubility Equation as defined in step 1 to get [AgX +]: Ksp = [Br −][Ag +] The analysis and procedure is fine, except the product in step 4 it's a little bit big. Check the algebra reorder there. The answer I get is 2 ⋅ 10 − 8 M. inauguration tv ratings
