    When is silver nitrate light sensitive?

    I apologize for the super basic question but I am about to mix some silver nitrate and I haven't been able to find out at which point it starts being light sensitive.
    I've seen videos where it is mixed in open light and even stored in clear glass bottles. I've gotten myself amber glass bottles.

    By itself, or mixed in distilled water, silver nitrate is not light-sensitive. Combined with halide salts, it becomes very light-sensitive, and combined with organic materials, somewhat light-sensitive.

    Organic (carbon) materials that can combine with the silver salts make it light sensitive. The other salts speed it up.

    An excellent question and some great answers. I've always wondered myself. Now...can someone explain how to turn a silver ingot into silver nitrate?

    If you watch the Youtube video "How Film Is Made" which is a Kodak industrial film from the 1950s you'll see them doing it.

    SIlver nitrate becomes light sensitive when combined with an organic substance. Look at your fingers after you get some on them.

    Add nitric acid.

    Please do avoid this. Silver nitrate is highly toxic.
