Best practice
Use "which is supposed" to clearly indicate the intended function, purpose, or expectation associated with a noun phrase. For instance, "This software, which is supposed to streamline the workflow, has actually made it more complicated."
Common error
Avoid using "which is supposed" when you actually mean "which was supposed to". The latter implies an unfulfilled expectation or a past obligation that was not met, while "which is supposed" refers to a current expectation.

FAQs
How do I use "which is supposed" in a sentence?
Use "which is supposed" to add nonessential information about a noun, indicating its intended function or expectation. For example, "The new filter, which is supposed to remove impurities, doesn't seem to be working."
What can I say instead of "which is supposed"?
You can use alternatives like "that is intended to", "that is meant to", or "that is designed to" depending on the specific nuance you want to convey.
Is it correct to say "that is supposed" instead of "which is supposed"?
While both "that" and "which" can introduce relative clauses, "which" is typically used for nonrestrictive clauses that add extra information, whereas "that" is used for restrictive clauses that are essential to the meaning of the sentence. "Which is supposed" is therefore preferable when the information is nonessential.
What's the difference between "which is supposed to" and "which was supposed to"?
"Which is supposed to" indicates a current expectation or intended function, while "which was supposed to" refers to an expectation or plan that existed in the past, often implying that it was not fulfilled. For example, "The report, which is supposed to be finished by Friday, is still in progress" versus "The report, which was supposed to be finished last week, is still not done."
