You can buy a caulk made for concrete, If the gap is large you can also install a foam rod first. Any hardware store or big box store.

That joint is very normal because of the construction process.
As Neal said, use a backer rod if the gap is large. Since the slab may move differently than the wall, you need a good, flexible caulk. But the best you can possibly find/afford and not the cheap junk because the cheap stuff is horrible to clean up if it fails.
