Answer:
H2SO4 + 2NaOH ==> Na2SO4 + 2H2O
Explanation:
Potassium will loss it's electron because it have a character of electropositively therefore it's electron will transfer to flouren which will make stable and complete of it's electro configuration. Now potassium will have negative charge due to loss it's outer most electron on it's orbit and flourine will take negatively charge too because of complete it's outer most shell to be completed.(But we have to know that at first flourine was had a positive charge because of not completed of it's outer most shell)
low melting point means that a low amount of heat is required to melt said substance.
