Question

Title Claim: Replace this text with the key claim(s) you have identified in the essay prompt. You should be able to state the claim(s) clearly in one or two sentences. Proposed Experiment Replace this text with a 300-500 word essay describing an experiment that would provide strong evidence in evaluating the claim you have identified above. This should not be a procedure or a research paper discussing or reviewing the topic. Instead, focus on elements of the design of an experiment a chemist could conduct in a laboratory to test the claim. Include details such as what you would measure, how you would measure it, how you would evaluate the data, and what the results would mean. Consider discussing limitations of the experiment or ways to further strengthen the experiment. Be sure to cite your references using the APA format (in text citations and references list). This is a chemistry class. Think about ways to test the claim using chemistry. For example, if a claim related to the amount of caffeine in coffee, it would be better to chemically measure the amount of caffeine than to survey participants on how much it helped wake them up. Do a little research on how that could be done. (# of words] References: Replace this text with your references.

Explanation / Answer

Here,the experiment I have taken is to measure the concentration of sodium hydroxide in 0.1 hydrochloric acid.

Balance Equation will be: NaOH + = NaCl + HCl

Measure 25ml of NaOH with the pipette and pour into the beaker. Take 100ml of HCl in the burette.Methyl orange indicator is added to NaOH.

Now titration in done till the yellow coloured solution changes to the orange colour. Measure the value of the burette where the colour is changing. This is repeated for 3 times. Get the average of the 3 measurements, let it be G.

Moles of HCl= concentration * cubic decimeter of G

From balance equation 1 mole of NaOH neutralises 1 mole of HCl, hence mole of Hcl =mole of NaOH in the beaker.

Concentration of NaOH =mole/ cubic decimetre of 25ml.
