Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Warming the solution of sulfuric acid and oxalic acid during redox titration increases the reaction rate, making the titration process faster and more efficient. The elevated temperature helps to ensure that the reaction between the two compounds proceeds to completion, resulting in more accurate and reliable titration results.
What is the specific heat of 10 percent sulfuric acid?
For any acid solution the specific heat can be arrived by weight average basis. For a 10% acid the sp.heat will be 0.1 * 0.345 Btu/lb F + 0.9 * 1.0 = 0.9345 Btu/lbF Specific heat of 10% Sulfuric acid is 0.9345 Btu/lb F or 3.9126 kJ/kgK
What happens when you mix sulphuric acid with distilled water?
When mixing sulfuric acid with distilled water, it generates heat. It is important to add acid to water slowly while stirring, as adding water to acid can cause a violent reaction. Diluting sulfuric acid with water results in a solution with lower concentration and is commonly done to prepare solutions for various applications.
Preliminary test for the identification of acetate ion?
Add a few drops of dilute hydrochloric acid to the solution to liberate acetic acid, then add a few drops of ferric chloride solution. The formation of a red/orange precipitate indicates the presence of acetate ions.
What happens when a solution of sulphuric acid is added to a solution of ammonium hydroxide?
When a solution of sulfuric acid is added to a solution of ammonium hydroxide, a neutralization reaction occurs. The sulfuric acid will donate protons to the ammonium hydroxide, forming water and ammonium sulfate salt. Heat may also be produced in the process.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
What is the enthalpy change of solution of oxalic acid?
Enthalpy of solution of oxalic, succinic, adipic, maleic, malic, tartaric, and citric acids, oxalic acid dihydrate, and citric acid monohydrate in water at 298.15 K
Test for ester?
Acid hydrolysis using sulphuric acid and water (equilibrium reaction). The ester splits into a carboxylic acid and alcohol, protons donated from the acid. The solution can then be distilled and the remaining acid can be checked using UV indicator. Acid hydrolysis using sulphuric acid and water (equilibrium reaction).

What is the specific heat of 20% sulphuric acid solution?
The specific heat capacity of a 20% sulfuric acid (H₂SO₄) solution can be estimated based on the specific heat capacities of its components (water and sulfuric acid) and their respective proportions in the solution. Here’s a step-by-step approach to estimate it: **Components in the Solution**: Sulfuric acid (H₂SO₄) Water (H₂O) **Specific Heat Capacities**: The specific heat capacity of water (H₂O) is approximately 4.186 J/g°C. The specific heat capacity of concentrated sulfuric acid (H₂SO₄) is around 1.38 J/g°C. **Calculation Method**: A 20% sulfuric acid solution means that for every 100 g of solution, there are 20 g of sulfuric acid and 80 g of water. **Estimation**: To estimate the specific heat capacity of the solution, you can use a weighted average based on the proportions of water and sulfuric acid: [ \text{Specific heat of solution} = (\text{% of water} \times \text{Specific heat of water}) + (\text{% of sulfuric acid} \times \text{Specific heat of sulfuric acid}) ] Given that 20% of the solution is sulfuric acid and 80% is water: [ \text{Specific heat of 20% sulfuric acid solution} = (0.80 \times 4.186) + (0.20 \times 1.38) ] Calculate the specific heat: [ \text{Specific heat of 20% sulfuric acid solution} = (3.3488) + (0.276) ] [ \text{Specific heat of 20% sulfuric acid solution} \approx 3.624 \text{ J/g°C} ] Therefore, the specific heat capacity of a 20% sulfuric acid solution is approximately **3.624 J/g°C**. This estimation assumes ideal mixing and that the specific heat capacities of water and sulfuric acid are accurate for dilute solutions around this concentration.

What happens if sulphuric acid is spilt on a hot summers day?
Well when the heat interacts with the sulphuric acid molecules it forms a covalent bond therefore causing rappid expasion turning into an explosive reaction

How do you prepare ammonium fertilizer?
the ammonium salt produced by a neutralization process, by reacting the ammonium hydroxide with dilute sulphuric acid. the amount of ammonia added into the sulphuric acid is enough when the amniotic smell produced. drop the ammonia little by little. then, heat while stir the mixture until the solution becomes 1/3 of the original volume. lastly, to obtain the salt, the filtration process should be done after the solution is cool.
