If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.
Use an indicator...? Beetroot and red cabbage work in the home if you don't happen to live down the street from a lab. I don't.
Dish liquid is designed to generate a lot of suds. A dishwasher cycle will stir up excessive suds that the machine won't be able to rinse away. Some dishwashers will stop or break down if this happens. If you're out of the regular dish washing detergent, rinse the dishes well before you put them in and then run the dishwasher without detergent. The hot water and dry cycle will sanitize dishes sufficiently. Or, put the dishes in, close the door and leave it until you can get some detergent.
There may be a chances of dysentry
nothing. cabbage is not dangerous to small creatures like tadpoles
Probably not, depends on where the clog is at and how the dishwasher drain is connected. I wouldn't chance it, but the worst that will happen is the sink will fill with the water from the dishwasher.
the colour of the indicator will increase
Seek urgent medical advise.
you will kill the plants
nothing as long as you ate other vegetables ;)
If a little bit, nothing. :P
The juice will turn red or pink
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
