2 Draw a line graph to illustrate your results. What will be on the x-axis and what will be on the y-axis? Give your graph a heading. 7 Conclusion: Do you accept or reject your hypothesis? Motivate your answer using your experimental results.

Here are the answers to the questions from the image: 6.1 Redraw the table in your answer sheet and present your results. Here is the table with hypothetical experimental results, assuming an experiment where white vinegar is added to a bicarbonate of soda solution, and vice versa, to observe pH changes. |l|l|l|l| Substance & Number of teaspoons of bicarbonate of soda/ white vinegar added & Colour of the universal indicator paper & pH of the test solution \\ Bicarbonate of soda & 0 (initial solution) & Blue & 9 \\ White vinegar & 0 (initial solution) & Red & 3 \\ Bicarbonate of soda & 1 teaspoon white vinegar added to bicarbonate solution & Green-Yellow & 6 \\ White vinegar & 1 teaspoon bicarbonate of soda added to vinegar solution & Orange & 4 \\ Bicarbonate of soda & 2 teaspoons white vinegar added to bicarbonate solution & Orange & 4 \\ White vinegar & 2 teaspoons bicarbonate of soda added to vinegar solution & Yellow-Green & 6 \\ 6.2 Draw a line graph to illustrate your results. What will be on the x-axis and what will be on the y-axis? Give your graph a heading. Step 1: Identify the independent variable for the x-axis. The independent variable is the quantity that is changed by the experimenter. In this experiment, it is the amount of white vinegar added (if observing the pH change of bicarbonate solution). x-axis: Number of teaspoons of white vinegar added Step 2: Identify the dependent variable for the y-axis. The dependent variable is the quantity that is measured and changes in response to the independent variable. In this experiment, it is the pH of the solution. y-axis: pH of the test solution Step 3: Provide a suitable heading for the graph. The heading should clearly describe what the graph illustrates. Graph Heading: Effect of White Vinegar on the pH of Bicarbonate of Soda Solution 7. Conclusion: Do you accept or reject your hypothesis? Motivate your answer using your experimental results. Step 1: State the hypothesis (assuming a common hypothesis for this experiment). A typical hypothesis would be that adding an acid to a base will decrease the pH. Hypothesis: Adding an acid (white vinegar) to a base (bicarbonate of soda) will decrease the pH of the solution. Step 2: Determine whether to accept or reject the hypothesis based on the hypothetical results from the table. Based on the hypothetical results where the pH decreased from 9 to 4 as vinegar was added, the hypothesis is supported. Accept the hypothesis. Step 3: Motivate the answer using the experimental results. The motivation should directly reference the observed changes in pH. Motivation: When white vinegar (an acid) was added to the bicarbonate of soda solution (a base), the pH of the solution decreased from an initial value of 9 (basic) to 6 (slightly acidic) after 1 teaspoon, and further to 4 (acidic) after 2 teaspoons. This observed decrease in pH demonstrates the neutralization of the base by the acid, which supports the hypothesis. Send me the next one 📸
