how does soap react with soda metal​

Answer 1

Hello❤

Soaps, will react with metal ions in the water and can form insoluble precipitates. To eliminate the metal ions in water, washing aids such as washing soda (sodium carbonate) and borax (sodium tetraborate) were added to the wash water. These compounds would precipitate the metal ions, eliminating most of the soap scum.
