Concept explainers
(a)
Interpretation:
The given reaction should be identified as whether precipitation, neutralization or redox reaction.
Concept introduction:
Reactions of ionic compounds can be grouped into three and they are,
- 1. Precipitation reaction: A precipitation reaction takes place when two solutions of well soluble substances together form a poorly soluble salt.
- 2. Acid- base neutralization reaction: it is a double displacement reaction in which an acid and a base react to form an ionic compound (salt) and water.
- 3.
Oxidation-reduction reaction: Both the oxidation and reduction reaction occurs together in achemical reaction . It is also known as redox reaction.
Change in the oxidation number of atoms involved in the reaction is one of the special characteristic of reduction reaction.
The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
(b)

The given reaction should be identified as whether precipitation, neutralization or redox reaction.

- The amino acid glycine is often used as the main ingredient of a buffer in biochemical experiments. The amino group of glycine, which has a pKa of 9.6, can exist either in the protonated form -NH or as the free base -NH2, because of the reversible equilibrium R-NH =R-NH₂ + H+ In what pH range can glycine be used as an effective buffer due to its amino group? pH 8.6 to pH 10.6 In a 0.1 M solution of glycine at pH 9.0, what fraction of glycine has its amino group in the -NH form?

- Glycine is a diprotic acid, which can potentially undergo two dissociation reactions, one for the a-amino group (NH), and the other for the carboxyl (-COOH) group. Therefore, it has two pK₁ values. The carboxyl group has a pK₁ of 2.34 and the α-amino group has a pK2 of 9.60. Glycine can exist in fully deprotonated (NH2-CH2-COO¯), fully protonated (NH3-CH2-COOH), or zwitterionic form (NH3-CH2-COO¯). Match the pH values with the corresponding form of glycine that would be present in the highest concentration in a solution of that pH. fully deprotonated form NH2-CH2-COO- fully protonated form NH–CH,–COOH zwitterionic form NH–CH,−COO Answer Bank pH 7.0 pH 11.9 pH 6.0 pH 8.0 pH 1.0arrow_forwardThe AG of hydrolysis of a sugar phosphate (S-O-P) to the free sugar (S-OH) is -26.6 kJ/mol in a hypothetical cell in which the steady-state concentrations of sugar phosphate, free sugar, and inorganic phosphate are 1.0 mM, 0.20 mM, and 50.0 mM, respectively.
