# The effect of sodium chloride nacl

Uses[ edit ] In addition to the familiar domestic uses of salt, more dominant applications of the approximately megatons per year production data include chemicals and de-icing. Discussion Graph 1 demonstrates a power relationship between the corrosion rating and the time observation days. This power relationship was the same for each line independent variable and can be proven by the R2 value for all the lines which was above 0.

The recorded results all represent R2 values which were 11 percent or less than the expected result of 1. For the control it can be seen that the R2 value is 0. Contrary to this accuracy and precision, the one percent solution of sodium chloride had an R2 value of 0. For the three percent solution of sodium chloride it had an R2 value of 0.

Following the same accuracy as the one and three percent sodium chloride solutions, the 10 percent sodium chloride solution had an R2 value of 0. This also shows a very accurate result as it was 6.

Lastly, the 30 percent solution of sodium chloride had the second most accurate and precise R2 value with 0. This demonstrates that it was only 1. The power relationship in graph 1 illustrates that for all the independent variables except for the 30 percent solution of sodium chloride solution, the amount of corrosion on the iron nails, according to the corrosion rating key, increased over time proving the expected positive gradient.

However, for the 30 percent sodium chloride solution the line remained relatively flat, thus meaning that the nail in the 30 percent sodium chloride solution rusted the least. In graph 1, section The effect of sodium chloride nacl the gradient of both the control and the 1 percent sodium chloride solutions were 1.

This means that there is not much difference in the rate of reaction at the start of the experiment. The gradients for both the 3 percent and 10 percent sodium chloride solutions were 1. The gradient of the 30 percent sodium chloride solution was 0. In section two of graph 1, it can be seen that there is a much wider range of results. The gradient of the control in section two stayed the same; however, the gradient of the 1 percent sodium chloride solution decreased to 0.

As for the gradient of the 3 percent sodium chloride solution the gradient was 0. For the 10 percent sodium chloride solution the gradient in section 2 was 1. The gradient of the 30 percent sodium chloride solution in section 2, was 0 and so it had a decrease of percent, and so as a result the corrosion rating stayed the same each observation day as there was no reaction happening.

Graph 2 demonstrates a polynomial relationship between the maximum corrosion and the percentage of sodium chloride solution. This polynomial relationship can be proven by the increase and decrease of the maximum corrosion rating over the percentage of sodium chloride solution.

It can also be proven by the R2 value which was a 0. The R2 value was extremely precise and accurate as it was only 1. The polynomial relationship in graph 2 demonstrates a peak at which the most corrosion can occur, and then after that larger concentrations of sodium chloride decrease the rate of corrosion.

The polynomial relationship demonstrates that from 0 to 10 percent of sodium chloride the corrosion rating increased over time, thus meaning that the amount of corrosion also increased. However, after the 10 percent solution of sodium chloride the low corrosion rating of the 30 percent sodium chloride caused the line to steep down and thus illustrate that the rate of corrosion decreases after the sodium chloride solution close to the 10 percent mark.

The cause of the polynomial relationship between the independent and dependent variable in graph 2 is the concentration of sodium chloride that can be dissolved in solution. Contrary to this enough sodium chloride increases the conductivity of the electrolyte since there are more ions in solution; which then increases the rate of corrosion.

The gradient difference between section and section two was a Therefore meaning that there was a The difference in the maximum corrosion rating for the control and 1 percent sodium chloride solution had 9. This was expected due to the fact that the control did not contain sodium chloride and so there was no substance to increase the conductivity of the solution.

There was no difference in the maximum corrosion rating for 1 and 3 percent sodium chloride solution; this would be considered an anomaly. The maximum corrosion rating for the 10 percent solution of sodium chloride was a 25 percent increase in the corrosion rating in comparison to the three percent solution of sodium chloride.

This would be expected due to the 10 percent solution being extremely close to the optimal percentage of sodium chloride, 11 percent. Lastly the biggest difference in corrosion rating came from the 10 percent solution of sodium chloride and the 30 percent solution of sodium chloride as there was a negative It was a negative decrease due to the gradient of the line being negative.

Surprisingly all the trials had the same corrosion rating relative to what they were already recorded as.

## Further information

The only other anomalies were that the 3 percent sodium chloride solution, trail 1 had green rust on compared to trial 2 which had brown rust what was expected. It can be found that the green rust formed as a result of the ratio between hydroxide ions formed in the reduction reaction and chloride ions in solution being higher than 1.

Another anomaly was found in graph 1, where the 10 percent and 1 percent corrosion rating on day 6 did not follow the trend pattern of their respective lines.If you notice any other effects, check with your healthcare professional. Call your doctor for medical advice about side effects.
