Who would most likely be required to work with sodium hydroxide?
a plumber
a gardener
a bricklayer

A plumber is most likely to work with sodium hydroxide. This powerful chemical is commonly used as a drain cleaner as it helps to dissolve grease, hair, and other blockages. However, plumbers must handle it with care due to its caustic nature, wearing protective gear to ensure safety during usage.

While a gardener may use various chemicals, sodium hydroxide is not typically among their tools. Instead, they focus more on fertilizers and herbicides that are beneficial for plant growth. Bricklayers, on the other hand, may come across this chemical when cleaning their tools or equipment but are less likely to interact with it regularly.
