Will a mac ssd (it already have the os x) boot on a pc?
No, it won't boot natively, nor will it even mount on a Windows machine without a 3rd party translator 'plugin' to be able to read HFS+ or APFS.
Further, if it's APFS then I think only Paragon make a translator - APFS for Windows
They also do one for HFS, but I think there are other alternatives - HFS+ for Windows 

Depending on what the macOS version was will depend on which of those you might need. HFS was default until Sierra, since then it's been APFS.
