On Google Translate, both of them are 'electrical appliances'
電化製品 is synonymous to 家電 or home/consumer electrical equipment such as cleaners, refrigerators, laundry machines, microwaves, and air conditioners.
電気製品 is less common and just means "electric products/devices" in general. Centrifuges, escalators, oscilloscopes are 電気製品, but they are usually not called 電化製品.
Although @naruto's answer already clarifies the current distinction between the two words, it may be good to know how come those two are differentiated.
電気製品 is literally "electric product" that covers everything it should. Meanwhile, 電化製品 is literally "electrified product", which is originally used to advertise a new modern lifestyle—now rather commonplace in developed countries—that replaces human power with that of electricity. Washing machine instead of washboard, vacuum instead of broom, refrigerator instead of cold closet, rice cooker instead of iron pot, etc.
So 電化製品 is a quite path dependent name, but still preferred when you refer to home appliances.
