diluted acid

Only diluted acid should be used to clean concrete surfaces.

Chemical cleaning of a coin with a diluted acid.

Preparation of the diluted acid can also be dangerous due to the heat released in the dilution process.

It has good resistance to ketones, ordinary diluted acids, and alkalines.

By long boiling with diluted acids it is split up into glucose and convallaretin.

Resistant to vegetable and animal fats, many types of oil and diluted acids.

A simple and safe solution is to pump diluted acid mixtures from surface into the well to dissolve the offending material.

The artist has shaped his devastated landscapes using his hands, his fists, tools and diluted acid.

The technique is mainly recommended for aqueous solutions, such as buffers, or diluted acids or alkalis.

Sodium peroxide (NaO) is used to oxidize the sample that becomes soluble in a diluted acid solution.

For mixtures (e.g., partly diluted acids in water), the acidity function depends on the composition of the mixture and has to be determined empirically.

In conventional lead-acid cells, the diluted acid is in liquid form, hence the term "flooded" or "wet" cells.

After adsorption, metals could be eluted using a diluted acid solution (0.5 N) and the cocoa shells could be reused for many adsorption/desorption cycles.

When a cell discharges, the lead and diluted acid undergo a chemical reaction that produces lead sulphate and water (see lead-acid battery for details of the chemical reaction).

As the chemical resistance of this pipe is lower than that of lined pipe products, its other applications are restricted to handling solvents, and solutions containing salt, diluted acids and alkalis.

The Company also produces bottles that are primarily made of PET which is a plastic resin that is a recyclable, durable plastic with strong resistance to heat, moisture and diluted acid.

If white residues of concrete salts are evident on the dried surface, remove by scrubbing, high pressure hosing and a very diluted acid wash (10 to 1), if necessary until the surface is clean.

Elution tests carried out using different concentrations of hydrochloric acid have shown that a good portion can be eluted using a short contact time (approximately 10 min) and a diluted acid solution (0.5–1.0 M).

Preparation of solutions greater than 6 M (35%) in concentration is most dangerous, as the heat produced may be sufficient to boil the diluted acid: efficient mechanical stirring and external cooling (such as an ice bath) are essential.

Ovens and grills : Lightly soiled equipment of this type may be cleaned by virtually 'hands-off' technique using a caustic cleaner and a solution of vinegar or heavily diluted acid cleaner both spray applied.

Reverse pipetting is more precise in dispensing small volumes of liquids containing proteins and biological solutions compared to forward pipetting, which is mostly used for aqueous solutions, such as buffers, diluted acids or alkalis.

Lab tests show the deposits can be simply removed by rinsing the mud with diluted acids, a process that takes only a couple of hours and, say the authors, would not have any environmental impact so long as the acids are not dumped in the ocean.

Ethylene propylene diene monomer (EPDM): good resistance to hot water and steam, detergents, caustic potash solutions, sodium hydroxide solutions, silicone oils and greases, many polar solvents and many diluted acids and chemicals.

VRLA cells have essentially the same lead-acid chemistry, but the diluted acid electrolyte solution is immobilized, either by soaking a fiberglass mat in it (hence: glass-mat batteries), or by turning the liquid into a paste-like gel by the addition of silica and other gelling agents (hence: gel batteries).
