solute-solute and solvent solute interactions. Description We will be mixing ionic compounds in solute-solute and solvent solute interactions. We will be combining sodium‚ potassium‚ calcium‚ magnesium‚ copper‚ iron‚ nickel and silver and some anions like chloride‚ sulfate‚ nitrate‚ oxalate‚ phosphate‚ and hydroxide. We will be seeing which one forms a precipitate or rings. Most likely the anions will be the insoluble. From there we will be making a flow chart that will go accordingly to our experiment

Calcinosis cutis is rare condition signified by calcium deposition in skin and subcutaneous tissues. In all cases of calcinosis cutis‚ insoluble compounds of calcium are deposited within the skin due to local and/or systemic factors. These calcium salts consist primarily of hydroxyapatite crystals or amorphous calcium phosphate. It is commonly seen in blacks‚ and no apparent gender predilection is noted (6‚7) From the pathogenesis point of view‚ the condition is classified as metastatic‚ dystrophic

When testing for cations/metals you could use a flame test this is the simplest and quickest way of test for cations another way that you could test for cations is a sodium hydroxide test this test consist of adding sodium hydroxide to test compound when coloured precipitate is formed them stop adding the sodium hydroxide and see what the cation is by using the table below‚ this table show what colour the precipitate is and any further results. Anion Precipitate colour Further results
