* how much Na2OH3 (sodium carbonate) solution should be diluted in 500ml of water? NaOH (I know that Peak Out containing 30% NaOH) is not good for development or is too strong (I have seno4007 but I don't know if it's good for this type of film, I know it's good for spray Positiv20)

* can you tell me in what products can be found Na2OH3

thanks

Na2OH3 doesn't exist - if you mean sodium carbonate, that's Na2CO3. Washing soda. Chances are your supermarket sells it.
