Then there is a solution of Potassium Iodine. These two mixtures react together to produce H₂. This is in the form of the foam/fizz. The indicator is the immedient growing of foam/fizz after these two are mixed. The fizz is an indicator because it means that it is giving off gas. The gas is a new substance so the bubbles indicate this new gas. ]]> 2018-02-23 19:37:09 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/234874385 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/234883039 In this experiment they take Sulfur Dioxide and Hydrogen Sulphide both dissolved in water and mix them together. These chemicals are really  smelly so he used a closed tubing system to mix them. When they were mixed it turned yellow. There was now solid sulfur in water that doesn't dissolve. This is a very smelly  reaction and smells like rotten eggs. Sulfur gives off a very unpleasant smell so when these are mixed and sulfur is created and you can smell it the smell gives you proof that the sulfur was created. ]]> 2018-02-23 19:53:48 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/234883039 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/234907815 2018-02-23 20:57:14 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/234907815 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235008731 In this reaction there are two solutions. One is 2mg of potassium permanganate dissolved in 50mL of distilled water. The other solution is 6g of sugar and 10g of sodium hydroxide dissolved in 750mL of distilled water. The purple solution will change to a blue, then green, then slower to a yellow-orange. This is because of the new chemical that was formed in the reaction. The new substance is tiny solid particles of manganese dioxide. If you sit long enough the new solid particles will settle at the bottom and the liquid will become clear. The evidence is the color change and the new substance formed. The reason it is a indicator is because molecules and atoms can radiate different light due to their makeup. When a new substance is made it may radiate different light/color than the others due to its makeup. ]]> 2018-02-24 17:55:21 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235008731 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235010998 Exothermic reaction.

This is a chemical reaction because a new substance is being created, ash. When the paper is burned it changes form to ash which is a new substance. A new substance is a indicator because it is part of the definition of a chemical reaction. ]]> 2018-02-25 00:35:25 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235037539 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235163978 This reaction is between Aluminum and Iodine. It is jump started by water. In this reaction water is a Catalyst or something that can speed up the chemical reaction. In this reaction Aluminum is a very reactive metal. The Iodine is a oxidant for a number of elements. The oxidation of Aluminum and Iodine is initiated with water and is highly Exothermic. The excess Iodine vaporizes forming a deep purple vapor. The new chemical formed is Aluminum Iodine. This reaction is very intense and hot. There is a flame after the reaction. Also Aluminum is highly flammable. This is an indicator because unlike heating a  ice cube the heat is the product of the reaction. ]]> 2018-02-25 23:12:54 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235163978 chloepolzin2022 https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235166259 You start with two beakers of distilled water. In one you add sodium hydroxide and in the other one you add copper sulfate. When you add one to the other you get the new substance Copper Hydroxide. It is formed with two liquids so it is a precipitate. In the third beaker you add Iron Sulfate and pour the sodium hydroxide in. The new precipitate is Iron Hydroxide and also has changed color. The solid that was formed from the liquid is evidence that something new was made so it must be a chemical reaction. ]]> 2018-02-25 23:30:12 UTC https://padlet.com/chloepolzin2022/j0176s712jqj/wish/235166259
