Salts

Buy sodium chloride, sodium hypochlorite, ammonium nitrate and 500+ more chemical salts in ACS, USP, food and lab grades.

Buy chemical salts online in the grade and purity your work calls for, from a supplier that puts the price on the page instead of behind a quote form. This category holds 591 products across 32 salt families, so whatever you're after, from plain sodium chloride to sodium hypochlorite bleach solutions, nitrates like ammonium nitrate, carbonates, sulfates, phosphates, acetates and citrates, it's probably stocked here. Grades run from Lab Grade for general use up to ACS Reagent Grade for analytical work, with USP and FCC Food Grade options for anything that ends up in food, drugs or supplements, and select food grade salts also carry Kosher and Halal certification.

Every product has its SDS and COA posted online, so QA and safety teams can review the specs before the order even ships. Sizes run from gram quantities and 500 mL bottles up to 55 gallon drums and 275 gallon totes on select salts, so a teaching lab restocking a shelf and a plant filling a tank both find what they need on the same page.

About Salts

A salt forms when an acid and a base react and neutralize each other, leaving behind a positively charged ion (like sodium or potassium) paired with a negatively charged one (like chloride, sulfate or nitrate). Unlike the acids on this site, most salts are solids at room temperature, dissolve readily in water, and carry no strong acid or base hazard of their own. That said, plenty of salts here have their own hazards. Sodium hypochlorite is a strong oxidizer, ammonium nitrate is an oxidizer used in explosives when mishandled, and some salts are simply irritants. Always check the SDS rather than assuming a salt is automatically safe.

COMMON APPLICATIONS

Buffers and pH control in labs, disinfection and water treatment with sodium hypochlorite, fertilizer production from ammonium nitrate and phosphates, food preservation with sodium benzoate and potassium sorbate, de-icing and brine solutions with sodium chloride, titration standards and reagents, dietary supplements from citrates and gluconates, and industrial processes like plating, dyeing and cleaning.

GRADES EXPLAINED

Lab Grade is the biggest group by far, good purity with no official monograph, for general lab and industrial use. ACS Reagent Grade meets American Chemical Society limits for analytical methods. USP and FCC Food Grade meet pharmacopeia or food standards, and that's where the Kosher and Halal certified salts sit. Reagent Grade covers prepared solutions made for specific procedures.

TYPES & GRADES AT A GLANCE

Chlorides

Sodium chloride and other chloride salts, for buffers, de-icing, titrations and food use.

Sulfates

Sodium and magnesium sulfate among others, used in reagents, drying agents and buffers.

Nitrates

Ammonium nitrate and related salts, for fertilizer, oxidizers and analytical standards.

Carbonates

Sodium carbonate solutions and solids, for pH adjustment, cleaning and buffers.

Phosphates

Potassium and sodium phosphate salts, for buffers, food additives and fertilizer.

Acetates

Buffer and reagent salts used across analytical and biotech work.

Citrates

Zinc citrate and other citrate salts, common in food, supplements and buffers.

Hypochlorites

Sodium hypochlorite solutions for disinfection, bleaching and water treatment.

Sorbates and Benzoates

Food grade preservative salts, several Kosher and Halal certified.

Frequently Asked Questions

Where can I buy chemical salts online?

Right here. Lab Alley carries over 500 salts across 32 families, from sodium chloride to ammonium nitrate to sodium hypochlorite, in Lab, ACS, USP and FCC Food Grade. Pick your salt, check the price, and order with no quote needed. Most in stock orders ship within 1 to 2 business days.

What actually makes something a salt, chemically?

A salt is what's left when an acid and a base neutralize each other. It's made of a positive ion, like sodium, potassium or ammonium, paired with a negative one, like chloride, sulfate or nitrate. Most salts on this page are stable solids that dissolve in water, though a few, like sodium hypochlorite and ammonium nitrate, carry their own reactivity and need careful handling.

Lab grade vs ACS vs USP or food grade, what's the difference?

Purity and standard. Lab Grade is solid, everyday purity without an official spec, and it's the cheapest option for general use. ACS Reagent Grade meets American Chemical Society limits for analytical work. USP and FCC Food Grade meet pharmacopeia or food standards, and that's the tier to buy if the salt is going into food, drugs or supplements.

Which salts are Kosher, Halal or food grade?

Only specific SKUs, not the whole category. Our Potassium Sorbate USP/FCC and Sodium Benzoate Food Grade are both Kosher and Halal certified, along with the FCC food grade sodium carbonate and sodium chloride USP options. Most industrial and lab grade salts, including our ACS and technical grades, carry no such certification. Always check the product title.

Do I need a permit to buy chemical salts, and can they ship to my home?

Most salts need no purchase permit and ship without restriction. A handful are different: ammonium nitrate is regulated as an oxidizer and may require a business, lab or school address, and concentrated sodium hypochlorite ships as a corrosive with its own limits. Each product page lists its specific shipping rules, so check there before ordering.

Which grade should I buy?

Match it to the job. General lab work, cleaning or industrial process: Lab Grade. A method that specifies ACS, or trace analysis: ACS Reagent Grade. Anything going into food, drink or a supplement: USP or FCC Food Grade. A specific concentration for titration or buffer prep: one of our premixed Reagent Grade solutions.

How is sodium hypochlorite different from other salts here?

Most salts on this page are stable and unreactive. Sodium hypochlorite is the exception. It is bleach, a strong oxidizer that slowly breaks down even in its original container, releasing available chlorine over time. Store it cool, out of direct sunlight, away from acids and ammonia, and check the How to Store Sodium Hypochlorite guide before you stock up in bulk.

Can I buy chemical salts in bulk?

Yes. Many salts here come in sizes from grams and 500 mL bottles up to 55 gallon drums, and select liquid salts like sodium hypochlorite are available in 275 gallon totes. For pallets or a recurring delivery schedule, request pricing through Bulk & Custom Chemicals. Autoship takes 10% off eligible repeat orders.
