Section 1 Lab: Physical and Chemical Homes
The purpose of this experiment was going to explore the chemical and physical properties of water piping metal, magnesium (mg), magnesium oxide, mossy zinc, sodium chloride, copper 2 nitrate, and copper (II) carbonate.
On each in the previous chemicals stated, I did so several experiments. I seen color, smell, the effects of temperature, the effects of frosty H2O, the consequence of hot H2O, the effects of a litmus test, the consequences of diluted HCI, and the effects of diluted NaOH. I created a table with observations from each research below. In each of these findings, I observed if there have been any changes in color, stench, if there are any emissions present, virtually any sounds present, if the option was sencillo, or perhaps the substance improved from solid to the liquid.
Observations and Results
Compound NameColorOdorEffect of HeatCold H2OHot H2OLitmus TestDilute HCIDilute NaOH MgMetallic silverNo detectable scent at space temperatureWhen the dry substance is put on heat, that stays precisely the same color. It creates gasses, and has a certain odor. There is also a sound contained in the substance also. My guess is that something is burning off in the substance, since after it is on high temperature for a certain amount of time, the sound, odor, and gasses end. When mixed with cold H2O, color and odor remain the same as the compound was at space temperature. Although the majority of the substance is definitely not soluble in the drinking water, I have to think that a small amount of it truly is. My reason for believing this is certainly that when this particular was put into the compound, the water started to be slightly over cast. When the INGESTING WATER is heated, color and odor remain the same as the compound did at room heat. The element is still certainly not soluble, just as it was certainly not in the chilly water. When a drop in the solution combined with cool normal water is put into the blue litmus newspaper, outside of the droplet location turns a deeper color of blue (or purple) and the centre is a lighter weight shade of blue. When a drop is definitely added to the red litmus paper (in my opinion pink), it remains the same color, except for a little area in the center of the droplet area that turns a very light tone of magenta. When HCI is included with the substance, it creates a great exothermic reaction. The test pipe becomes hot, and the material makes a fizzling sound whilst bubbling. The substance remains to be the same color, and includes a slight stench (I believe that the odor might be from the HCI in addition than the substance. ). The perfect solution is not soluble in HCI. The moment NaOH was added to the substance, this stayed the same color. I did not notice virtually any odor. The substance had not been soluble inside the NaOH. CuRed-brown (copper color)No detectable scent at area temperatureWhen the dry substance is placed on heat, this changes to a dark brown color. It creates zero gasses or odor that we noticed. The moment mixed with frosty H2O, color and smell remain the same as the substance i visited room temperatures. The element is certainly not soluble in the cold normal water. When the WATER is warmed, color and odor continue to be the same as the compound was at area temperature. The substance is not sencillo in the chilly water. If a drop of the solution combined with cool drinking water is put into the blue litmus paper, outside of the droplet place turns a deeper color of blue (or purple) and the middle is a lighter weight shade of blue. Each time a drop is usually added to the red litmus paper (in my opinion pink), it keeps the same color. When HCI is included in the substance, it creates a great does not receive hot like the other tests. The element remains the same color, though the HCI becomes tinted a rather yellow color. There is a moderate odor (I believe that the odor could possibly be coming from the HCI more so than the substance. ). The majority of the answer is not really soluble in HCI, nevertheless I believe some of it may be. My spouse and i came to this conclusion following observing the slight color change in the HCI. Once NaOH was added to...
