Many undergo dangerous chemical reactions if they contact incompatible chemicals such as oxidizing materials, or if they are stored improperly. The Material Safety Data Sheet and the supplier's labels on the containers should tell you about all the hazards for the flammable and combustible liquids that you work with. These experiments require the expertise of a teacher or Professors Mom & Dad. Concentration vs. Rate of Reaction Learn what happens when the atoms’ and the reactants’ worlds collide. While the composition of a chemical substance is not altered by physical changes (such as freezing and evaporation), chemical changes, or reactions, result in the formation of new substances when bonds are formed and/or broken. Some relatively simple but common types of chemical reactions are illustrated in this experiment.
Examples of designs could involve chemical reactions such as dissolving ammonium chloride or calcium chloride. Assessment Boundary: Assessment is limited to the criteria of amount, time, and temperature of substance in testing the device.
Keep the mixtures in the hood until after you add the 10 ml of distilled water after completely dissolving the copper. Transform [Cu(H 2 O) 6] 2+ (aq) to Cu(OH) 2 (s) Be careful in handling NaOH, for it is a strong base which will sting if it contacts the skin. Add the NaOH solution dropwise to the copper solution.
