In a strong alkali, universal indicator typically turns dark blue or purple. This color change indicates a high pH level, usually around 12-14.

What are elements to the left called?

Elements to the left of the periodic table are called metals. These elements generally have low ionization energies and tend to lose electrons to form cations. They are good conductors of heat and electricity.


Difference between s-block metals and d-block metals?

the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.


What is formed when an acid neutralizes an alkai?

Salt and Water is formed. Acid + Base = Salt + Water Hydrochloric acid + Sodium hydroxide = Sodium Chloride + Water HCI + NaOH = NaCI + H2O


Which is more concentrated -20g of alkali in 250 cm3 of solution or 10 g of the same alkai in 500 cm3 of solution?

To determine which solution is more concentrated, we need to calculate the concentration of each solution in grams per cubic centimeter (g/cm3). For the first solution with 20g of alkali in 250 cm3 of solution, the concentration would be 20g / 250 cm3 = 0.08 g/cm3. For the second solution with 10g of alkali in 500 cm3 of solution, the concentration would be 10g / 500 cm3 = 0.02 g/cm3. Therefore, the first solution with 20g of alkali in 250 cm3 of solution is more concentrated at 0.08 g/cm3 compared to the second solution with 10g of alkali in 500 cm3 of solution at 0.02 g/cm3.

What is a neturalisation reaction?

A neutralization reaction is a reaction between and acid and a base forming a salt. Usually water is formed too, but not always. Arrhenius acids and bases always produce water, but acid-alkai reaction produce water and a metal salt.
