unknown sample are silver and iron. I know this because the precipitates and the colors of the elements precipitates matched therefore making the unknowns identifiable. 2. Write a net ionic equation for each of the following steps in the qualitative analysis scheme. a) Separation of silver ions‚ Ag+ Ag + (aq) + HCl(aq) AgCl(s) + H+(aq) Ag +(aq) + H+(aq) + Cl-(aq) AgCl(s) + H+(aq) Ag+(aq) + Cl-(aq) Ag+Cl-(s) b) Confirmation of silver ions‚ Ag+ AgCl(s) + 2NH3(aq) Ag(NH3)2+(aq) + Cl-(aq)

Qualitative Analysis Of Cations: Ca2+‚ Ba2+‚ Mg2+‚ Zn2+ and Al3+ OBJECTIVE: • To identify the cations in known and unknown samples. • To construct a logical flow chart for identifying the components of a mixture of unknown cations. INTRODUCTION: In this experiment we will study about qualitative analysis of cations: Ca2+‚ Ba2+‚ Mg2+‚ Zn2+ and Al3+. Qualitative analysis is an analytical procedure in which the question ‘what is present?’ is answered. In a systematic qualitative analysis scheme‚

at my clinic. We seem to use our ultrasound and our gastrointestinal scope more frequently when we are concerned about a foreign body‚ mass‚ infection‚ gastrointestinal lining of the stomach etc. So‚ I chose to use a stuffed animal and administer barium via a gastrointestinal tube. If this would have been a real animal I would have chosen to have it fasted for at least 12 hours to ensure a completely empty stomach‚ intestines‚ and colon. Because I used a stuffed animal it is quite hard to see anything

Simple qualitative analysis involves the identification of the constituents of an inorganic substance or a mixture of substances. The inorganic substances are split-up into two types of charged particles one of which is positively charged and the other is negatively charged. The charged particles are called ions or radicals. The positively charged ions are called cation or basic radical. The negatively charged ion is called anion or acid radical. In the qualitative analysis of an inorganic substance

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment
