Depends on what metal and what acid. Most common metals can be attacked by some type of acid. Other more rare and exotic metal are more resistant. Gold Platinum are resistant to almost all acids except for a mixture of Nitric and Hydrochloric acid (aqua regia) and in the case of platinum the mixture must be hot. Tungsten and Tantalum are also in this category. The only metal that is completely resistant to all acids at any temperature is Iridium, a platinum group metal. So the answer would be Iridium.

Is acid resistance a physical or chemical property?
Acid resistance is primarily a chemical property. It refers to the ability of a substance to withstand the corrosive effects of acids through chemical reactions, such as neutralization or passivation. This property is determined by the chemical composition and structure of the material, rather than its physical characteristics like size, shape, or color.
Is acid resistance a chemical change?
Acid resistance itself is not a chemical change; rather, it refers to a material's ability to withstand exposure to acidic substances without undergoing degradation or alteration. A chemical change involves a transformation where the chemical composition of a substance is altered, leading to the formation of new substances. Acid resistance can be a property of materials that are chemically stable in acidic environments, but the resistance itself does not constitute a chemical change.
Do batteries have resistance?
Yes they do have a resistance. Even though a battery is a voltage source it has some thevenin resistance. Every lead plate and cell of sulfuric acid, will have a small resistance. The thevenin resistance is equivalent or sum of all those resistances.
Is polyester acid resistance?
no as acids are corrosive they dmage irreversibly most of the materialsl
What acid is in vitamin c?
Ascorbic acid. It is a food supplement needed by human. It increases the body's resistance to infection. It also acts as an antioxidant.
Does platinum dissolve in nitric acid?
Platinum does not dissolve in nitric acid, which is why it is commonly used in jewelry and other applications that require resistance to corrosion.
Sometimes acid-fast bacteria accept the spore stain and spores accept the acid -fast stain-why?
This phenomenon occurs because acid-fast staining detects the presence of mycolic acid in the cell wall of bacteria, which is resistant to decolorization by acid-alcohol. Spores, which have a thick protein coat that is resistant to staining, can sometimes retain the acid-fast stain due to this resistance. Conversely, the resistance of acid-fast bacteria to decolorization can allow spores to be stained if present.
Does nocardia have mycolic acid?
Yes, Nocardia does have mycolic acid in its cell wall. Mycolic acid is a characteristic component of the cell wall in members of the genus Nocardia, which are classified as acid-fast bacteria due to their resistance to acid-fast staining procedures.
How does phosphoric acid affect the corrosion resistance of stainless steel?
Phosphoric acid can decrease the corrosion resistance of stainless steel by promoting the formation of localized corrosion, such as pitting and crevice corrosion. This is due to the acid's ability to break down the protective passive film on the stainless steel surface, making it more susceptible to corrosion.
Is PVC acid resistant?
Certain grades of PVC are resistant to acids, with improved resistance at higher molecular weights. However, PVC may not be suitable for highly corrosive or concentrated acid applications as it can soften or degrade over time. It's always best to consult with a chemical compatibility chart or supplier for specific acid resistance information.
What lipid is responsible for the acid fastness of acid fast organisms?
Mycolic acid is the lipid responsible for the acid-fastness of acid-fast organisms. It is a wax-like lipid found in the cell wall of bacteria such as Mycobacterium and Nocardia, contributing to their resistance to acid-fast staining techniques.
Does soapstone react to acid?
Soapstone is resistant to most acids and is generally considered chemically inert. It is commonly used in laboratories and kitchen countertops due to its acid resistance.
