The magic of water to wine to milk then to beer

Wow you must be amaze to see water can change to wine then to milk and then to beer. See Video. 

Actually is all based on chemical reaction. Below are the chemical that is placed in each glass before doing the demostration. I actually named the glasses A - D.

1.    Glass A (Water) – Pour 110ml of deionised water into the glass. Add in 20ml of saturated sodium bicarbonate with 20% sodium carbonate.

2.    Glass B (Wine) – Add a few ml of phenolphthalein into the wine glass. 

3.    Glass C (Milk) – Pour 25ml of saturated barium chloride solution into the glass.

4.    Glass D (Beer) – Pour 4ml of concentrated hydrochloric acid into the glass. Add in 5ml of bromothymol blue (0.1g in 8ml NaOH and top up to 250ml).

The explaination:

When Glass A is poured into glass B, the colourless water turned red, resembling wine. This is beacause Sodium Bicarbonate and Sodium Carbonate are alkaline which change the Phenophthalein from colourless to deep red (depending on the conc of the phenophthalein, the more concentrated, it will resemble more like wine).

When the ‘wine’ from glass B is poured into glass C, the solution turns milky white, resembling milk. This is because the barium chloride will react with the sodium carbonate to form barium carbonate which is a white precipitate and make the solution turns white and resemble milk. Since it is not alkaline anymore the phenophthalein change back to colourless.

When the solution from glass C is poured into glass D, the solution turns into a clear yellow solution with bubbling, resembling beer.This is because the barium carbonate reacts with the acid, forming soluble barium ions, water, and carbon dioxide gas. The white solid dissolves, the carbon dioxide creates bubbles. The bromthymol blue which turns yellowish-brown in acidic solution, gives the colour of beer.
