chemical substances test (dissolved in water) By Katia Ebaid ,Tala ALwazani ,Tia Karadsheh
Testing salt in water : 1) We can use salt in our daily lives by cooking and we can use it also for taste. 2) When we dissolve salt in water an endothermic reaction occurs, this is because the temp. of the solution is often a little lower than the temp. of the water in which the salt is dissolved.
Testing sugar in water: 1) Sugar is a useful product that we use in our daily lives for baking desserts and taste. 2) When sugar is dissolved in water it is an endothermic reaction in nature. The solubility of sugar in water will increase in temp.
Testing baking soda in water: 1) Baking soda is a substance that is common for baking and chemical reactions. 2) When baking soda dissolves in water it turns out to be an exothermic reaction in water, in conclusion the water gets a little warmer this is because the binding energy of the chemical bonds of the product has an excess over the binding energy of the components.
Testing borax in water: 1) Borax is mostly used for washing clothes, laundry and creating entertainment such as slime. 2) When borax dissolves in water it creates an exothermic reaction , this means that the energy taken away by the reaction is larger than the energy that is necessary to initiate the reaction.
testing vinegar in water: 1) People use vinegar mostly for cleaning vegetables and fruits 2) Vinegar is soluble in water, which forms an exothermic reaction, meaning that heat is a product in the reaction.
