The only reason you're asking this question is because your chemistry instructor has posed it to you. Think about what happened in lab: You synthesized the indigo, but it wouldn't dissolve in water to dye your cloth sample. So, you reduced it with sodium dithionite, whereupon it turned to a yellowish-green color. Then, you dyed your fabric, and let it dry. What happened when it dried? What makes your blue jeans blue?
When you heat copper hydroxide and sodium nitrate, a chemical reaction occurs where the copper hydroxide decomposes to form copper oxide and water, while the sodium nitrate decomposes to form sodium nitrite, oxygen gas, and nitrogen dioxide gas.
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
Assuming they are dissolved in water the mixture turns green. Presumably the copper and chloride associate and the sodium and sulphate remains clear. The cystalised substance remains green although the colour deepens when it is dry.
Sodium hydroxide turns red litmus paper blue.
yes it will stain peroxide unstains cloths i tryed it and it turns your jeans white and red.
most BLUE jeans are BLUE. if you get jeans that aren't blue then they are just jeans.
When sodium hydroxide is mixed with bromothymol blue, the solution turns blue due to the alkaline nature of sodium hydroxide. This indicates a basic pH level.
forever in blue jeans.
Sodium chloride water solution is neutral.
Blue Jeans are used as clothing
'des jeans' or less frequently 'des blue-jeans'
I believe that Blue Jeans is Arabian.
you would say you're wearing blue jeans because a pair means to so if you say, "i'm wearing a pair of blue jeans." that mean you are weaing 2 blue jeans lol x SO MAKE SURE YOU SAY I AM WEARING BLUE JEANS!
