iba kaya...yung household pagbukas walang fumes..yung industrial may usok..at mas mabilis yung industrial grade...nonetheless household grade ok rin medyo mabagal lang compared sa industrial..

parehas muriatic. hehehe.

nyahaha...dito samin marami ang dalawang klase na yan..pati yung Aqua Oxinada dalawang klase rin..

sa volumes cguro nagkakaiba kung ilang percent, household at industrial

TAMA! meon 10% meron naman 20% volumes

ma try nga yang hydrogen peroxide+salt+vinegar na yan...
bagal kasi ng etching sa ferric chloride

thanks sa mga info

Yung muriatic sis dalawang klase yan..yung pang household at industrial strength....pero same price...at least dito sa amin...yung industrial ginamit ko ang bilis ng etching...

Ano nga pala sir ang proportion ng muriatic ACID saka H2O2?

your most RIDICULOUS man :) · « **Reply #68 on:** November 02, 2011, 11:03:58 AM »

Masmakakatipid ba kung ganitong etching solution gagamitin natin?

Yung asin mura

Yung vinegar sa tindahan lang ni aleng Nena

Yung Hydrogen Peroxide Magkano

Tapos mas efficient po ba ito? I mean pwede pa ulit gamitin yung solution after use?

i bought muriatic acid( concentrated) and hydrogen peroxide (20%), yesterday at SM, hope to mix them soon and etch some copper boards..

sana makuha ko tamang timpla..

Ikasamoko · « **Reply #73 on:** November 03, 2011, 09:57:57 AM »

you don't even need a brain para dito...

1 Muriatic + 2 Hydrogen Peroxide..

remember to ADD ACID to Hydrogen Peroxide NOT the other way around..

pishboy · « **Reply #74 on:** November 03, 2011, 09:04:21 PM »

i think the solution is the same as HCl + H₂O₂
acetic acid = CH₃CO₂H (according to wikipedia
salt = NaCl
Cl + H = HCL right?
so you end up with HCl and Na + CH₃CO₂ which can react into Sodium acetate?
Pa-clarify, theory only...

Alin nman po ang mag-react sa copper?

Johannah Aleksandria · « **Reply #77 on:** November 03, 2011, 11:27:26 PM »

Napag-isip ko tuloy dapat ganito ang formula.

2HCl + H₂O₂ + Cu₂ = 2CuCl + 2H₂O

Hydrogen ion is removed from HCl, with it being aqueous, and reacts with the reactive oxygen from the peroxide to form water, leaving the Chlorine ion react and combine with the metallic copper to form copper chloride.
But HCl will not react with the metallic copper without the hydrogen peroxide because copper is not much reactive than hydrogen to Chlorine.

So dapat pala ang ratio ay 2:1
2 Muriatic + 1 H₂O₂

hehe, sorry po but i stand corrected to other ideas base on theory.

Small theory as to why I think the salt vinegar agua oxinada solution is similar to the HCL H2O2 solution
It's not really an explanation kung bakit sya nakaka-etch.
Again theory only, IDK if it's true. I'm partly sure for the acetic acid + salt = HCl but not sure with the HCl and Na + CH3CO2 into sodium acetate. Sorry if i'm wrong but i'm open to correct answers.

Tama ka nga, pareho nga lang sila.
Sodium acetate lang yung nadagdag.
Vinegar + Hydrogen Peroxide + Salt = Muriatic acid + Hydrogen Peroxide + Sodium acetate.
Ganun lang ang kinalabasan, ang kailangan lang maitama ay gaano kadami ang bawat isa. Pero dahil gumana na yung proportion na naibigay sa una, sundin na lang.
