How do YBCO superconductors react with hydrochloric acid?

[Mayhem]

If we consider YBCO 123, YBa₂Cu₃O_7-δ, what would the expected reaction if dissolved in aqeuous HCl? I have tried to find resources about this online, but the closest I got was related to Cl-containing YBCOs, and not actual reaction stoichiometry.

My intuition tells me the metal centers (Y, Ba) are not immediately affected as they are contained in the oxygen/copper cage. Rather, I'd expect products like copper chloride(s).

Update: It turns out it reacts to form Y³⁺, Ba²⁺, Cu²⁺ and Cu³⁺ ions as well as chloride and water.

Let our YBCO superconductor have the formula YBa₂Cu₃O₇. Then the reaction with hydrochloric acid solution proceeds according to the following equation:
YBa₂Cu₃O₇ + 13HCl → YCl₃ + 2BaCl₂ + 3CuCl₂ + 6.5H₂O + O₂.

This and some other reactions of YBCO superconductor are described in the follow NASA article: https://ntrs.nasa.gov/api/citations/19920010156/downloads/19920010156.pdf.

Is there a question in there? Or are you just posting a fact?

I just found a suitable article for the question that Mayhem asked.

It's true but about 6 months too late.

Yeah, I wanted to post my answer 6 months ago but had an issue with logging into account.
