1. Baking soda turns 1.turmeric red
2.purple cabbage juice green
3.red litmus blue
4.all of the above

D) all of the above

Explanation:

Turmeric, purple cabbage juice (containing anthocyanin), and litmus paper all act as indicators which help us to detect whether a particular substance is acidic or basic.

In basic medium, turmeric changes it's colour to red, purple-cabbage juice turns to green and red litmus turns to blue.

Baking soda/Sodium carbonate Na

is basic in nature and thus causes the above changes in the indicators.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
