No. 100% silver would be pure silver. Noble silver, Argentium nobalis. which is super soft and shiny. it is very difficult to tarnish.
Silver solder is an alloy. An alloy being a mixture of metals. Hard solder is around 67% silver eg. the amount of silver generally goes down as its melting temperature goes down. Soft solder is likely around 45% eg. it could vary massively from company to company and application.
A recipe for hard solder is. 1/2 parts tombac brass, to 1 part pure silver. Adding 5% zinc to this, would lower its melting temperature enough to call it softer solder for aplication.
Caution, careful of this recipe for jewelry application. it might not meat your countries standard for silver content and you could be breaking the law. Research the percentage of silver necessary to meat the requirements. do not add metals to it you know nothing about. You could hurt someone. All of this should be do buy someone with good knowledge.
No.
Yes, silver solder can be used on any color of gold---however, the joint will be white and will tarnish more rapidly.
You can't because part of the coin is from another material, if you melt out the silver you are still left with the other material. So the coin is made from 90% silver 10% something else.
Solder is a fusible alloy that is used to join less fusible metals or wires,Combinations of tin and lead are most common, in ratios of 60 percent tin to 40 percent lead; 63 percent tin to 37 percent lead; and 50 percent tin to 50 percent lead.
Use lead-free solder, 0.2 percent lead or less. Lead free means NO Lead your better off with a silver bearing alloy as it has a longer pasty range or 95% tin 5% antimoney Actually the term "solder" means lead bearing according to the AWS specifications
No.
If it's silver solder, very little. If it's not silver, nothing.
Silver jewelry requires that you use silver solder for repairs. It is silver based where common solder is lead or tin based. Standard solder is too acidic and will corrode the jewelry. It can probably be found on e-bay. Or ask a jeweler where he or she gets it.
Silver solder.
Silver solder.
If you're looking for treasure, it is not there. However, there are types of solder that have silver in it so there may be traces of silver in the solder joints on your motherboard.

Solder is manufactured in hundreds of different grades and compositions for thousands of different applications. Solder that might be described as "Silver solder" is most commonly commercially manufactured in about 50 different compositions with silver contents of up to 40% and is priced accordingly. Silver solder is often used in jewellery making and repair, engineering and many electrical manufacturing processes.
Typically one solders sterling silver with silver solders. There is not a solder called "sterling solder." You can choose from an array of silver solders ranging from easy (extra soft) through hard. Soft solders have lower silver content and melt at a lower temperature. Hard solders have higher silver content and flow at higher temperatures. If you are doing multiple solder joints on a single piece of solder you will need to use several grades of solder. However, if you are just creating a single solder joint than it is best to use a soft or medium solder.
