Repeat the above activity using alkalis such as sodium hydroxide, calcium hydroxide solutions etc., instead of acid solutions.
Does the bulb glow ?

Sodium hydroxide solution is used in testing _____

Acetylene is acidic but it does not react with sodium hydroxide or potassium hydroxide. Give reason.

Write a balanced chemical equation with state symbols for the following reactions. (i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (ii) Sodium hydroxide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.

The sodium hydroxide solution at the surface reacts with the CO_(2) in the atmosphere to form

How many grams of 40% pure sodium hydroxide is dissolved in 0.5 M, 250 ml NaOH solution?

The pH of a 0.001 M aqueous solution of sodium hydroxide will be

Calculate the molarity of a solution containing 5g of Sodium Hydroxide (NaOH) in 450 ml solution.

Refer to the Activity 3 in the chapter. Start with distilled water. The LED would not glow. Add two drops of some acid to distilled water and check the glow of LED. Add two more drops and check the intensity of the glow. Repeat the activity 5 to 6 times by adding 2 drops of the same acid each time. Do you see any difference in the intensity of glow with increasing acid content of water? What can be inferred from the above observations? Repeat the entire activity by taking a solution of baking soda and adding drops of it to distilled water instead of acid. Write differences and similarities. (AS_(3),AS_(1))

Calculate the weight of sodium hydroxide present in 200ml of 0.5 M solution.
