Experiment Hard Clam Juvinles term Toxicity: Introduction: Our testing involves exposing Hard clam juvinle to an interval of AgNo3 concentrations or a test sample for the purpose of determining the concentration or dilution levels that would cause the death of 50% of the organisms (LC50) exposed over 24 h and meeting the conditions defined by this method. If necessary and possible‚ the following may also be determined: a) the concentration level that causes the death of 20 % of organisms exposed

They will then be immersed in diluted sodium hydroxide at 85 celcius. Next‚ the shells are then washed with di-ionized water and demineralized to remove calcium carbonate by treating them in diluted hydrochloric acid at room temperature. In the 2nd phase‚ chitin will then be dissolved in less than 40% of Sodium Hydroxide‚ and heated to 90celcius which will convert

Why some water samples can be harder than others (1)Hard water is any water containing an appreciable quantity of dissolved minerals. (2) Some of the minerals come from chalk‚ limestone or marble‚ which the water may have flowed over or through. (4) Hard water contains calcium or magnesium ions. Limestone‚ marble or chalks are insoluble in pure water however they will dissolve slowly in acidic rain. If your water has emerged through limestone or chalk (calcium carbonate) it will be hard. (1) Soft
