For the given titration curve, the color observed prior to equivalence point, at the equivalence point and after the equivalence point have to be given when thymol blue is used as indicator. Concept introduction: Acid-base titration is titration between acid and base. It is also known as neutralization reaction. There are primarily four types of acid-base titrations – Strong base vs strong acid Strong base vs weak acid Weak base vs strong acid Weak base vs weak acid Equivalence point ensures the titration reaction becomes completed and at this point the number of moles of titrant and the number of moles of analyte remain equal. We cannot see the completion of titration reaction – the titrant and the analyte becoming equal in stoichiometric proportion , hence we use a chemical compound called indicator called which indicates the end of the reaction by color change. The end point refers to the color change and indicates equivalence point has been reached.

Interpretation Introduction

Interpretation:

For the given titration curve, the color observed prior to equivalence point, at the equivalence point and after the equivalence point have to be given when thymol blue is used as indicator.

Concept introduction:

Acid-base titration is titration between acid and base. It is also known as neutralization reaction.

There are primarily four types of acid-base titrations –

Strong base vs strong acid

Strong base vs weak acid

Weak base vs strong acid

Weak base vs weak acid

Equivalence point ensures the titration reaction becomes completed and at this point the number of moles of titrant and the number of moles of analyte remain equal. We cannot see the completion of titration reaction – the titrant and the analyte becoming equal in stoichiometric proportion , hence we use a chemical compound called indicator called which indicates the end of the reaction by color change. The end point refers to the color change and indicates equivalence point has been reached.

The reaction for obtaining NO2 from NO and O2 has the rate equation: v = k[NO]2[O2]. Indicate which of the following options is correct.(A). This rate equation is inconsistent with the reaction consisting of a single trimolecular step.(B). Since the overall order is 3, the reaction must necessarily have some trimolecular step in its mechanism.(C). A two-step mechanism: 1) NO + NO ⇄ N2O2 (fast); 2) N2O2 + O2 → NO2 + NO2 (slow).(D). The mechanism must necessarily consist of three unimolecular elementary steps with very similar rate constants.

a. What is the eluent used in the column chromatography here (a “silica plug filtration” is essentially a very short column)? b. The spectroscopy of compound 5b is described in the second half of this excerpt, including 1H-NMR and 13C-NMR (which you will learn about in CHEM 2412L), MS (which you will learn about later in CHEM 2411L) and IR. One of the IR signals is at 3530 cm-1. What functional group does this indicate might be present in compound 5b?
