muriatic acid

[rich_2137]

Hi all

Iv'e just been to my local chemical shop they told me that muriatic acid is the old name for Hydrochloric acid if this is true then i do't need to buy any because i already have some or is it a case that muriatic acid is a lower concentrated Hydrochloric acid??

Thanks
Richard

Same chemical but it's sold in an assortment of concentrations. What does the label say?

muriatic acid is 32% hcl and concentrated reagent grade is 35% hcl, you cant get any more concentrated than that at ambient temps at (1) atmospheric pressure. muriatic acid from your local home improvement supply works just fine for refining. check the label and make sure its 32%.

Thanks for the fast reply
My hcl is 36.2% so i will need to dilute or just check my home improvement store for a 32% concentrate

A range of concentrations near 30% is fine no need to dilute, some have found 14% and that would be an issue. You're in good shape.
