Acid + Base -> - correct answer Salt + Water Molarity (M) - correct answer Number of moles per liter Titration of Vinegar - correct answer First drops will cause brief appearance of pink that quickly fades Near endpoint, more of the flask will turn pink but still fade after a few seconds Endpoint When entire flask turns pink and stays that way without adding another drop Buffer - correct answer - Solution that resists a change in pH when a small amount of acid or base is added ...

ACS BIOCHEMISTRY Solved Exam |100% Pass| Henderson-Hasselbach Equation *Ans* pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis *Ans* Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) *Ans* Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography *Ans* Separates sample based on ...

What is acidosis correct answer: a ph below 7.35 What is alkalosis correct answer: a ph above the reference 7.45 Normal range of ph correct answer: 7.35-7.45 How does the lungs help regulate ph correct answer: retention or elimination of co2 by changing the rate or volume of ventilation How do the kidneys regulate ph correct answer: excreting acid and reclaiming HCO3 from the glomerular filtration What is the formula for henderson-hasselbach equation correct answer: PH= HCO3...
