The concentration of dilute sulfuric acid can be determined by titration with sodium hydroxide solution of known concentration. Below is a method to carry out this titration practical.
1. 25.00cm3 of dilute sulfuric acid was measured out using a pipette and transferred to a conical flask.
2. A few drops of methyl orange indicator were added to the acid in the conical flask.
3. Sodium hydroxide solution was added to the acid from a burette until the indicator changed colour.
4. The titration was repeated twice more and the accurate result was the average of the three results obtained.
Explain TWO details that could be added to this above practical method to ensure an accurate method is obtained

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
