Calculate the molarity of the calcium ion in this solution.
After adding a few drops of Eriochrome Black T indicator, the EDTA solution was titrated with the standard calcium ion solution from part ii until the reddish tinge turns to blue at the endpoint. A drop of methyl orange indicator was added followed by drops of 6M sodium hydroxide until the indicator turned orange to neutralise the solution.
The solution was then made up to cm3 in a volumetric flask. This solution was then titrated with 0. The indicator turned blue after On titration with 0.
A bulk solution of hydrochloric acid was standardised using pure anhydrous sodium carbonate Na2CO3, a primary standard.
The solution was then transferred, with appropriate washings, into a graduated flask, and the volume of water made up to cm3, and thoroughly shaken with stopper on! The aliquot required Q14 For this question, the relevant formula mass and equation are in the answers to Q Q15 a Describe a procedure that can used to determine the molecular mass of an organic acid by titration with standardised sodium hydroxide solution.
Indicate any points of the procedure that help obtain an accurate result and explain your choice of indicator. A few drops of phenolphthalein indicator were added and the mixture titrated with 0. Q16 Using the method outlined in the answer to Q15 a0.
If the concentration of the alkali was 0. Q18 Using the method described in the answer to Q15 asodium hydroxide solution can be standardised. Q19 The solubility of calcium hydroxide in water can be measured reasonably accurately to 3sf by titrating the saturated solution with standard hydrochloric acid.
In the calculation below assume the molarity of the standardised hydrochloric acid is 0.
HCl and hence calculate the moles of them involved in the titration. In the pharmaceutical industry, aspirin is manufactured by reacting 2-hydroxybenzoic acid salicylic acid with ethanoic anhydride. Prior to this reaction, 2-hydroxybenzoic acid is manufactured by reacting carbon dioxide with phenol, the mixture is heated under pressure sodium hydroxide in the so called Kolbe Reaction.Single replacement reaction with copper replacing silver in solution.

Look over the graded report before you submit the next lab report. suppose a piece of reddish-gold copper metal is placed into a colorless silver nitrate solution.
After thirty minutes, a gray solid can be observed on top of copper-colored. Mole Ratios. Copper and Silver Nitrate.
Introduction The reaction of copper wire and silver nitrate in aqueous solution provides an interesting display of chemistry in action delicate silver crystals begin to grow on the wire surface and the color of copper(II) ions gradually appears in solution.
