Chemistry: Atoms First
- Proteins are complex biological molecules made of smaller molecules called amino acids. Five common amino acids and their Ka values are listed below. Rank them from strongest to weakest acid. Amino acid KaKaK_{\rm a} glutamine 6×10−3 arginine 2×10−2 threonine 3×10−3 tryptophan 4×10−3 proline 1×10−2arrow_forwardWould CH3NH3C2H3O2 (salt) be neutral, basic, acidic or cannot be determined?arrow_forwardMethylamine CH3NH2 is a weak base with pKb =3.36. What is the value of Ka for thetrimethylammonium ion, CH3NH3+?A) Ka = 4.4×10–4 B) Ka = 10.64 C) Ka = 2.29×10–11 D) Ka = 2.88×10–13arrow_forward
- What is Ka for the conjugate acid of C₅H₅N (Kb = 1.7 × 10⁻⁹)?arrow_forwardThe simplest amino acid is glycine ( molar mass = 75.1 g/mol), whose structure is shown above. An aqueous solution of glycine is prepared by dissolving 0.329 g in 150 mL of water at a temperature of 25 C. The resulting solution has a pH of 2.02. Calculate the molarity of the solution. Calculate the percent ionization of this solution of glycine. Calculate the Ka for glycine. Glycine is water soluble. On a structural formula like the one above, draw one water molecule that shows how glycine and water can form hydrogen bonds with each other.arrow_forwardCalculate Kh using the equations, whichever is applicable.If the ion is a conjugate acid of a weak base, then Kh = Ka.If the ion is a conjugate base of a weak acid, then Kh = Kb. Calculate Ki using, KiKh = KwIf Kh = Ka, then Ki = Kb.If Kh = Kb, then Ki = Ka.arrow_forward
- In charts the pKa of acids are often given instead of the Ka values. For the 5 acids below predict which will have the largest pKa value. HClO₄ H₂SO₄ H₂SO₃ H₂SeO₃ H₂SeO₄arrow_forwardThe pH of a 0.24 M solution of dimethylamine is 12.51. Calculate the Kb value for dimethylamine (4.4 × 10−4) Calculate Kb for F- if Ka for HF is 7.1 x 10–4. Polyprotic Acids and Mixture of Acids please help me with this problemarrow_forwardWhen 0.1000mol of an unknown acid, represented by HA, are dissolved in enough water to make 1.000L of solution the resulting pH is 2.20. Calculate the value of Ka for HA. Calculate the pH of a solution made from dissolving 0.100mol of acetic acid (HC2H3O2) in enough water to make a 1.00L solution. The Ka of formic acid (HCHO2) is 1.7x10-4. Calculate Kb of the formate ion, CHO2- Determine the pH of a 1.0M solution of (CH3)3NHCl. Kb =6.3x10-5 for trimethylamine, (CH3)3N.arrow_forward
