Finding out the accurate concentrain of sulphuric acidAimThe point of this investigation is to find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate.H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2Acid + Alkali à Salt + Water + Carbon dioxideRatio of sulphuric acid to sodium carbonate:H2SO4 : Na2CO31 : 1Concentration of sulphuric acid:H2SO4 is approximately 0.05 - 0.15 moldm-3The average concentration of the sulphuric acid is:0.05 + 0.15 = 0.1 moldm-32Concentration (moldm-3) = concentration (g dm-3)Molar mass (g mol-1)Mr of Na2CO3 = (23 x 2) + ( 16 x 3)= 106 g mol-1250cm3 x 0.1moldm-3 x 106 gmol-1 = 2.650g1000cm3I will use 2.650g of Na2CO3 in 250cm3 of distilled water.Apparatus· Weighing bottle· Clamp stand· Glass rod· 250cm3 volumetric flask· Small conical flask· 50cm3 burette· 100cm3 beaker· 25cm3 pipette· Pipette filler· Plastic pipette· Small filter funnel· Balance· Distilled water· Sulphuric acid· 2.650g of sodium carbonate· Spatula· White tile· Methyl orange indicatorMethod· I will make a solution where the solute will be the sodium carbonate and the solvent will be distilled water.· I will first measure the weighing bottle on its own without the lid on.· I will then make the weight of the bottle equal to 0.00g on the balance.· I will add 2.650g of sodium carbonate using a spatula.· I will then pour the sodium carbonate into a beaker, which has been washed out with distilled water to remove unwanted compounds.· I will weigh the mass of the weighing bottle without the lid on.· I will add distilled water to the beaker, drop by drop to make a viscous solution in order to reduce the amount of solid formed.· I will add approximately 100cm3 of distilled water into the beaker.· I will use the glass rod to stir the solution and get rid of solid forms.· After the sodium carbonate has dissolved completely in the distilled water, I will wash out the sodium carbonate into the volumetric flask. I will do this twice with 100cm3 of distilled water.· Then I will add slightly less than 50cm3 of water to the beaker and pour that into the volumetric flask.· Then I will use a pipette to add distilled water to the volumetric flask up to the 250cm3 line and will make sure that I can see the bottom of the meniscus reach the line at eye level.

Determination of an unknown amino acid from a titration curve

1691 words - 7 pages AbstractExperiment 11 used a titration curve to determine the identity of an unknown amino acid. The initialpH of the solution was 1.96, and the pKa's found experimentally were 2.0, 4.0, and 9.85. The acceptedpKa values were found to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 whilethe accepted value was found to be 183.5. The identity of the unknown amino acid was established to beglutamic acid

Investigate the Effect of Varying Solution Concentration on Osmosis in a Potato Chip

4330 words - 17 pages Investigate the Effect of Varying Solution Concentration on Osmosis in a Potato Chip Prediction A definition of osmosis is: 'the movement of water molecules from an area of high water concentration to a low water concentration across a semi-permeable membrane' (Oxforddictionary 2000). In a high concentration of water the amount of solute (e.g. sugar) is low. These solutions are usually known as a dilute or weak solution. But in a low

Investigating the effect of varying concentration on the reaction between magnesium ribbon and hydrochloric acid

1903 words - 8 pages more of the products. Figure 3 shows the concentration of the hydrochloric acid increased so there are more particles to have more successful collisions. This is a faster reaction then the original reaction. The final reaction has the same amount of particles of acid and the magnesium, but the magnesium has been cut to increase the surface area. This makes the acid particles more likely to have more successful collisions each second than the

The elements were determined quantitatively by titration with ethylenediaminetetraacetic acid (EDTA). This method is valued as a good estimate and is used widely because of its use of common lab equipment. Only a single column was run for each metal in the interest of time. To acquire a meaning for the effect that the method has on the

A region of high concentration of water is either a very dilute solution of something like sucrose or pure water. In each case there is a lot of water: a high concentration of water. A region of low water concentration is the opposite of the above, i.e. a very high concentration of sucrose solution: a
