2.Add water/base to neutralise the acid, then wipe it off with a cloth.
3. Add acid to water. When acid is poured into water, it flows down the flask and mixes much better, so no boiling occurs & the energy released due to acid water interaction is absorbed by water which is present in larger amount as compared to acid.

2. Dilute with water,and neutralise it with alkali, and mop/wipe it up

3. Water to acid, so that acid will not be spilt

Use a test tube holder while heating the test tube.

Q2- Put excess baking soda to neutralise the acid and pick up the solid formed and dispose of it

Q3- Add acid to water. This is because when water is added to acid, an extremely concentrated acid solution is formed. A lot of heat is released, solution may boil violently when heated and may splash out.

Q4- B (25.7ml)

Q5- grams

2.Contain and soak up spill with absorbent that does not react with spilled product. Place used absorbent into suitable, covered, lavelled containers for disposal.

3.Adding water is safer thr case of it spilling some of its contents; with acid, spilling a small part of its contents can be harmful.

1. First ensure the test tube is placed in a water bath or use test tube holder to hold the test tube over direct heat.

3. Acid to water because if water to acid the first drop of water will react with the acid

When you heat a solution in a test tube, use a test tube holder and face the opening of the test tube away from you, as there may be gas escaping. Gloves may offer more protection in case of any spillage of chemicals.

2.) Neutralise the sulphuric acid with a suitable base solution, then wipe the liquid away with a paper towel or sponge.

3.) I would add the acid into the water because because if it was done vice versa, the water would fizzle on contact with the surface of the acid, causing a potential hazard

4.) 26.35 ml

5.) Milligrams
