The advantages of plasma sources over the flame sources for emission spectrometry needs to be explained. Concept introduction: Plasma sources spectroscopy a kind of mass spectrometry that detects metals as well as non-metals of low concentrations as one part in 10 15 (part per quadrillion, ppq) on the low-background isotopes that involves plasma. Flame emission spectroscopy is a traditional method of spectroscopy. In this method, quantitative measurement of the optical emission obtained from the stimulated atoms are used to determine the concentration of an element that is to be analyzed.

Question

43) 10.00 ml of vinegar (active ingredient is acetic acid) is titrated to the endpoint using 19.32 ml of 0.250 M sodium hydroxide. What is the molarity of acetic acid in the vinegar? YOU MUST SHOW YOUR WORK. NOTE: MA x VA = MB x VB

Interpretation Introduction

Interpretation:

The advantages of plasma sources over the flame sources for emission spectrometry needs to be explained.

Concept introduction:

Plasma sources spectroscopy a kind of mass spectrometry that detects metals as well as non-metals of low concentrations as one part in 10¹⁵ (part per quadrillion, ppq) on the low-background isotopes that involves plasma. Flame emission spectroscopy is a traditional method of spectroscopy. In this method, quantitative measurement of the optical emission obtained from the stimulated atoms are used to determine the concentration of an element that is to be analyzed.
