Sorcerer/Warlock spells known

I have Sorcerer/Warlock

When you get new known spells going up a lvl as a sorcerer, can you select spells with only a warlock prerequisite?

Welcome to FGU.

See the section in Chapter 5 of the PHB Multiclassing and Feats. You can use the spell slots for Warlock spells and the pact magic spells for sorcerer spells. You select spells on level up depening on whether you are leveling up the Warlock or the Sorcerer.
