Muriatic acid is a (concentrated) solution of Hydrogen chloride, which is a GAS (at STP). So it is not a liquid itself and certainly NOT a DRY solid!
Properties of concentrated muriatic or hydrochloric acid (HCl in water):
Density 1.18 g/cm3 at concentration (variable) value for assay 36-38% w/w
Muratic acid is hydrogen chloride (HCl) dissolved in water and sold as a liquid
To lower pH levels in an inground pool, you can use pH decreaser chemicals, such as sodium bisulfate or muriatic acid. Follow the manufacturer's instructions when adding the chemicals to the pool water, and regularly test the pH levels to ensure they remain within the recommended range of 7.2 to 7.6. Additionally, consider using aeration or adding baking soda to stabilize the pH levels.
Well, honey, you can't just snap your fingers and turn dry acid into liquid acid. You'll need to dissolve the dry acid in a specific amount of water to create a liquid solution with the desired concentration. Just follow the instructions on the dry acid packaging to determine the correct ratio of dry acid to water for your desired concentration. It's not rocket science, but it does require a bit of measuring and mixing.
You can try using a stainless steel cleaner or a mixture of baking soda and water to remove the black stain caused by the muriatic acid. Apply the cleaner or paste to the affected area and scrub gently with a soft cloth. Rinse thoroughly with water and dry the stainless steel surface.
Hydrogen chloride is a gas, Hydrochloric acid is the acid. ( difference is in solution )
One gallon of muriatic acid weighs approximately 9 pounds, and it typically contains about 31-38% hydrochloric acid. To calculate the weight of dry acid in one gallon of muriatic acid, you would need to consider the concentration of hydrochloric acid in the solution.

I tried both types of acid. The pH Minus (dry acid) and then the muriatic acid. I did not have much luck at all with the total alkalinity (TA) dropping with the dry acid. When I used the muriatic acid the TA dropped within a couple of days. So to answer your question I'd have to say the muriatic acid. It is much cheaper ($12 a case) at Leslie's Pool Supply and probably cheaper other places. The muriatic acid was also quicker and had better results.
You can add dry acid to your pool when your pH is above 7.8
Muriatic acid can deteriorate over time if not stored properly. Exposure to air and moisture can lead to a reaction that degrades the acid's strength. It is recommended to store muriatic acid in a tightly sealed container in a cool, dry place to maintain its effectiveness.
use either muriatic acid or dry acid (sodium bisulfate)
Apply muriatic acid to dry surface (good ventilation a must). This removes stains and oils. (Note: if you plan on using an acid stain, DO NOT clean with muriatic acid, since this will make acid staining impossible). Rinse and dry. Apply sodium hydroxide (10% solution) to neutralize remaining acid. Rinse and dry. Ready for your choice of floor treatment. Recommend a urethane sealant first, to prevent moisture absorbed in concrete from coming up under the coating you finish with.
One inexpensive substitute for pH minus is muriatic acid, which is available at hardware stores. However, it is important to handle muriatic acid carefully as it is a strong acid. Another option is sodium bisulfate, also known as dry acid, which can be used to lower pH levels in pools and is available at pool supply stores.
Where to Get Muriatic AcidMost pool stores carry this kind of liquid acid. If not they all carry "Dry Acid" of "Sodium Bisulfate". Each pound of Sodium Bisulfate is the same as using 10 ounces of Muriatic Acid in pool water. Here are more opinions and answers from other FAQ Farmers:You can usually find Muriatic acid at Home Depot next to all the pool supplies.I buy Muratic Acid at Albertson's Grocery store believe it or not.I heard from pool dealer that this product is very toxic try Lo'n Slo from Bioguard instead.Loon in the paint section of hardware and lumber stores. It is not toxic to the pool.Here's the cheapest way: go to a pool store and buy pH decrease. 10 parts water to 1 part decrease.I get my acid from a dealer dealing with cleansers such as bleach, dishsoap etc. Muriatic acid is the best and easiest way to reduce pH levels, but it has many other uses to.You can buy muriatic acid in the Outside Garden section near the pool supplies at any of the Home Depot stores.
There are 3 principal chemicals for lowering pH: muriatic acid, sodium bisulfate (dry acid) & CO2. If this is a commercial application then CO2 may be a viable source. The sodium bisulfate is dry acid which when mixed with water makes liquid acid but does not have the odor. Muriatic acid and sodium bisulfate both lower total alkalinity at hte same time as lowering the pH. CO2 may raise total alkalinity at the same time as lowering pH. The total alkalinity is important to have a stable pH which in turn is important to have a relatively constant pH for the proper effectiveness of the sanitizer (chlorine) Any other questions feel free to email me direct.

Muriatic acid is the preferred chemical. You can also use dry acid (sodium bisulfate, pH down)) which is a bit easier to use but does increase sulfates, which can be detrimental to plaster surfaces, can foul salt cells, and is much more expensive to use.
When using Muriatic Acid it's important to wear the proper protective gear, and have plenty of clean water on hand in case of an accident. Always pour the acid into water, and not the other way around. Wet the stones before cleaning. Dilute the acid with water. Make sure the stones are soaked with water before applying, and don't leave the acid on too long. Scrub the stains with a scrub brush. Rinse everything off, and allow to dry.
