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

Being lactose intolerant means that people cannot digest lactose products properly. This condition effects people at all different levels. The symptoms being shown with this are bloating‚ diarrhea‚ gas‚ and nausea. This condition is due to the large intestine not being able to break down the lactose into glucose‚ because of the lack of enzyme lactase. In order for the large intestine to work properly it needs certain dairy products such as yogurt to help with digestion. When a person id lactose intolerant

Solubility product The Solubility product is related to SPARINGLY SOLUBLE SALTS ONLY!!!!! Examples are silver chloride‚ lead(II) chloride‚ calcium sulphate (in other words‚ it deals with salts commonly called insoluble salts) Consider a sparingly soluble salt MX Imagine the reaction that occurs when the solid is placed in water aMX (s) + H2O [pic] aMn+ (aq) + bXm- (aq) The equilibrium expression would be [Mn+]a [Xm-]b [MX]a [H2O]

The aim of this experiment it to analyze the solution of Ba(OH)2 of an unknown concentration. In order to obtain the quantitative analysis‚ the exact amount of a particular compound or element present in sample‚ two procedures were performed. The first procedure was by conductimetric titration and by gravimetric determination. The conductivity was analyzed during the reaction between the sulfuric acid (H2SO4) and barium hydroxide (Ba(OH)2). Through the conductivity‚ the equivalence point can be determined;
