WebSTEP 1: Set-up the ICE Table STEP 2: Use the equilibrium constant expression and solve for x 1.7× 10−4 = [HCOOH][H+]×[HCOO−] Remember the approximation (x < 0.30) [HCOOH] = (1pt) and [HCOO−] == . (1pt) STEP 3: Based on your calculations, the value of [H+]. Is equal to . . (2pts) Calculate the pH of the buffer. Show your solution below: (5pts) WebRemember highest ph means smallest hydrogen ion concentration, since all solutions are 0.40 molar the weakest acid has the smallest Ka. 0.056 g of CH3COOH (Ka = 1.8 10-5) is dissolved in enough water to obtain 50.0 mL of solution. The concentration of H+ in the solution is _____. A) 1.8 10-4 M. B) 1.8 10-3 M. martin\u0027s grocery covid vaccine

WebCalculate the pH of a 0.0145 M aqueous solution of formic acid (HCOOH, Ka = 1.8×10-4) and the equilibrium concentrations of the weak acid and its conjugate base. pH = [HCOOH]equilibrium = M [HCOO- This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebJan 10, 2024 · The conjugate base of a strong acid is a very weak base, and, conversely, the conjugate acid of a strong base is a very weak acid. Strong acids are H3O plus, HNO3, H2SO4, HCl, and HBr. Negligible acids are HS minus and OH minus. Stron bases are O negative 2, S negative 2. Negligible bases are NO3 minus, HSO4 minus, Cl minus, and … WebYes, the conjugate base of the first reaction can also react with another water molecule, eg: H2SO4 + H2O -> HSO4- + H3O+ HSO4- + H2O -> SO4 2- + H3O+ H2SO4 and HSO4- are conjugate acid-base pairs, and HSO4- and SO4 2- are also conjugate acid-base pairs ( 7 votes) Darmon 6 years ago martin\u0027s grocery deli trays
