Chapter 16.9, Problem 1RC

(a)

Interpretation Introduction

Interpretation:

The weakest anion has to be identified from the three X- of salts NaX (X=A, B, or C)

Concept Information:

Salt hydrolysis is a reaction in which the ion of salt reacts with water and produce either hydronium ion or hydroxide ion.

Based on ions produced in solution through salt hydrolysis, the salt can be classified as,

Acidic

Basic

Neutral

Conjugate acid = Base + H+

Conjugate base = Acid − H+

Conjugate acid-base pairs differ by only one proton.

(b)

Interpretation Introduction

Interpretation:

The three X- anions from three salts NaX (X=A, B, or C) has to be arranged in order of its increasing base strength.

Concept Information:

Salt hydrolysis is a reaction in which the ion of salt reacts with water and produce either hydronium ion or hydroxide ion.

Based on ions produced in solution through salt hydrolysis, the salt can be classified as,

Acidic

Basic

Neutral

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
