Yellow! Fa sho!
When we resperate, we release carbon dioxide. Plants take that in to make oxygen. BTB can not do anything with the carbon dioxide. Only if you add a plant in the container with the BTB, you can make it it's blue color again. A fun experiment is to add soda, like coke, to BTB and see if it changes.
The color becomes diluted. For instance if you add white to black the black looses it's rhythm and can't jump as high.
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
To prepare a 20 g/500 mL solution of NaOH, you would gradually add 20 g of NaOH to 500 mL of distilled water while stirring until fully dissolved. It is important to add the solid to the liquid to prevent splattering. Remember to always use caution and appropriate personal protective equipment when handling NaOH due to its caustic nature.
To achieve a pH of 8.0, you would need to add NaOH (sodium hydroxide) to increase the pH. NaOH is a strong base that will react with water to produce hydroxide ions, which will raise the pH. Adding HCl (hydrochloric acid) would lower the pH as it is a strong acid.
Soda effects BTB when you add it to the BTB. Soda has carbon dioxide in it, which makes it foamy. BTB is used as an indicator of chemicals with a weak acid and base. When you add the carbon dioxide it will change into a green like color.

Nothing.
yellow-green
Add a base, such as NaOH, NH3, or LiOH

In this case sodium zincate is formed.

Adding gray to a color desaturates it, making it appear less vibrant and more muted. The more gray that is added, the closer the color becomes to a neutral gray itself.
To prepare 0.1N NaOH solution from a 1N NaOH solution, you can dilute 1 part of the 1N solution with 9 parts of water (since 1/10 = 0.1). Measure 1 volume of the 1N NaOH solution and add 9 volumes of water to it, then mix well to get your 0.1N NaOH solution.
