Final answer:
Silver, tin-silver, or tin-copper solders are indeed safer than lead-based solders because they eliminate health risks associated with lead exposure, and their properties offer various benefits over traditional lead-based solder.
Step-by-step explanation:
True, silver, tin-silver, or tin-copper solders are considered safer to use than lead-based solders. Lead, used in traditional solder, poses health risks, particularly when used in plumbing or electronics that may come into contact with food or sensitive environments. Modern alloys such as those with tin and silver (tin-silver solder) or tin and copper (tin-copper solder), have been developed as safer alternatives
They do not contain lead, thus eliminating the health risks associated with lead exposure. The properties of these metal alloys also offer various benefits; for example, tin improves the solder's wetting properties and lowers the melting point, while silver provides strength and electrical conductivity.
