Why does BTB turn green?

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.


When you add white to a hue you get what of that color?

The color becomes diluted. For instance if you add white to black the black looses it's rhythm and can't jump as high.


What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?

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.


How is a solution of NaOH prepared dissolving 20g of NaOH in 500ml of distiled water solved?

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.


As edta dissolves in water the h will increase to achieve a pH 8.0 would you need to add hcl or naoh?

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.

How does soda effect BTB?

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.

How does a color change if you add more gray to it?

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.


How do you prepare 1 N to 0.1N NaOH solution?

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.
