ALDON Innovating Science Copper (II) Chloride Solution, 0.5M, 500mL - The Curated Chemical Collection

My neighbor used this to remove already in his pond. I use it in my pool. Only need a small amount and it works better than any pool algea you can buy.

Arrived as described. Worked like a charm for my purposes.

I used this with hydrochloric acid mixed together to bring back the serial numbers on a gun that had gotten stolen and found but the person that stole it tried to grind the serial numbers off. I did not take any before shots but you could only see part of the first number and part of the last number before I started

Used this on a fire pit for a boy gender reveal party and it worked great. Couple sprayed it on and fire stayed blue for a long time.

I am not sure what scientific applications this would be good for but it did NOT do well for Electroforming Jewery. It turned a dark teal color, had a crust on top and I kept burning stuff. I ordered solution from Rio Grande and have not had any issues since. I am thinking the concentration was not meant for plating jewelry but would work for other applications so I left 3 stars.

It worked great for my home school project.

I use this product for darkroom photograpy process and it works really well and much more affordable here then other websites.
