What happens when calcium chloride sodium bicarbonate and phenol red solution and water are mixed together?

Equation of reaction:

2NaHCO3 + 2HIn^- + CaCl2 ---------> CaCO3 + 2HCl + 2Na-In^- + H2O + CO2 (water remains unchanged)

Where H2In^- = Phenol red indicator

1. Heat is evelved durinf the reaction indicating an exothermic process taking place.

2. Effervesence occurs indicating that a gas has been evolved.

3. CaCl2 and NaHCO3 react to produce an acid (HCl).

4. Phenol red is an indicator. It turns yellow in the presence of an acid.

: A colour change is observed (from dark pink to yellow) indicating the formation of HCl.

In conclusion determine what all items in reaction do?

Like what each one does or how they react? or how one supports each other?

Phenol red 6.4-8.0 at 6.4 it is still yellow but as the solution becomes more basic, it turns red. which compound above is a base? CaCl2 or NaHCO3

You mix all those together and you just created a shampoo. Good job.

what is NaHCO3?
