Introduction of TOPIC

Aim- To find how hexaqua ions reacts with various substances (other ions)

Equipment

* Goggles

* Apron

* 5 test tubes

* Beaker

* Pipette

* Hydrochloric acid

* Copper hexaqua

* Cobalt hexaqua

* Chromium hexaqua

* Ammonia

* Sodium Hydroxide

* sodium carbonate

Method-

* We collected our five boiling tubes and set them up in the test tube rack

* We collected the ion we were going to use (the cobalt) and measured about 5cm of it and poured it in each of the boiling tubes

* We put a few drops of HCL in each of the boiling tubes containing the cobalt, we then had to swirl the solution and observe what was happening, then add a few more drops to excess it and see how it changes

* We noted the results of what we observed in a table like the one below

* We Repeated the same process with other chemical ions (chromium and copper)

Risk assessment

Chromium hexaqua can be toxic, medium risks; can cause problems in the body such as breathing or lungs problems if inhaled too much. Hexaqua ions are quite acidic because of their pH, 3+ ions are more acidic than 2+ ions.

Exposure to cobalt hexaqua during long period of time can cause health risks such as damages to the lung

Hydrochloric acid is a very corrosive substance and therefore can seriously damage the eyes and skin. It can also cause problems to the respiratory tract by inflaming it. It can also cause severe burns to organs inside the body. Swallowing causes severe irritation and tissue destruction of the oesophagus and the digestive tract which may be fatal.

The sodium hydroxide is also corrosive which means it can burn the skin when in direct contact with it.

Swallowing copper haxaqua can cause harm; it can cause Irritation to the eyes and skin. It can also be very toxic to aquatic organisms, might cause long-term adverse effects in the aquatic environment.

Conclusion

According to my results, most of the ions reacted with the other chemicals (HCL, sodium Hydroxide, the sodium carbonate, the pH and the ammonia). We can see from my table the different colour changes the ions go through with every chemicals and we can also the texture some of them obtain. For example in the presence of ammonia, the chromium went from liquid to a solid state.

Evaluation

I am satisfied with the way the investigation went and the results I obtained from it. However there are some changes that I could make to it if I was to do it again. I was to repeat that investigation, I would make sure I measure out the right amount of ions and chemicals I need to carry out my investigation as the mount of chemical can make a difference to the outcome of the investigation.

Examining the Solubility of Substances in Double...

Aim: The aim of this investigation is to perform various double replacement reactions with known substances and record the qualitative observations. Furthermore, writing the equations for the reactions and apply the rules of solubility to see if every color change equals to a precipitate. It is predicted that a solid will form only when there is a change in color. Plan: Materials: * ZnSO4 solution * BaCl2 solution * AgNO3 solution * Pb(NO3)2 solution * NaCl solution * NaBr solution * CuSO4 solution * NaI solution * Na2SO3 solution * Na2SO4 solution * Pipette * 45 test tubes * Test tube rack Procedure: Mix one drop of each of two solutions in different test tubes and recorded observations. Safety: During the experiment a protective coat and goggle must be worn to prevent contact with the chemicals. Results: This is a table showing the observations while mixing the solutions. Analysis: ZnSO4...

The Reaction Time

The focus of this study was to investigate how the participation of different sports activities affects the reaction time. Two hypotheses were established based on my research question: "People who carry out sports should have a faster reaction time than those who do not" and "The sport where a fast reaction time is most important, thus where training sessions focus on improving it the most, should have a participants with faster reaction time than the sport where a fast reaction time is less important". The sports chosen were boxing, badminton, stationary bicycle, judo and swimming. A control group was included. In every group there were 20 participants where 10 subjects were women, 10 subjects were men, 10 subjects in the age group 10-17 and 10 subjects in the age group 18-40. The test was carried out using a reaction timer software installed on a laptop. The results showed that people...

Rate Of Reactions Of Yeast And Glucose,...

Aim: The aim of this experiment is to compare the rate of reactions of the reaction of yeast with the three different carbohydrates, namely glucose, sucrose, and lactose. Hypothesis: The rate of reaction should be fastest in the reaction between yeast and sucrose, since sucrose is broken down to two molecules of glucose, thereby giving more glucose for the yeast to act on. Therefore, for the same amount of glucose and sucrose, there will ultimately be double the amount of glucose in sucrose because the yeast will break down the sucrose into two times the amount of glucose. Theory: The three carbohydrates being used in this experiment fall into two categories; monosaccharide and disaccharide. Glucose is a monosaccharide, whereas sucrose and lactose are disaccharides. One sucrose molecule breaks down to give two molecules of glucose, and a molecule of lactose breaks down to give a molecule of glucose and a...
