The solubility of barium sulfate (BaSO₄) in water is extremely low, typically around 0.0002 grams per liter at room temperature. This translates to approximately 0.2 parts per million (ppm). Due to its low solubility, barium sulfate is often used as a radiocontrast agent in medical imaging.
What else can I help you with?
Why is barium sulfate good shield against gamma rays?
Barium Sulfate is used as a radio contrast agent for radio imaging. Radio Contrast agents are those agents which improve the visibility of body parts in the process of X RAY. Barium is a heavy metal with a high atomic number of 56. Thus it absorbs radiations such as X Rays or Gamma Rays better than other metals thus preventing the radiation exposure to our body. Thus it is used as a shield against gamma rays.
What USB solubility of a solute usually expressed in?
USB solubility of a solute is typically expressed in terms of concentration units such as molarity (moles per liter), mass percent, or parts per million (ppm). These units indicate how much solute is dissolved in a given volume of solvent, reflecting the solute's ability to dissolve under specific conditions. Understanding solubility is crucial for applications in chemistry, biology, and environmental science.
How do you make bordeaux mixture?
To make bordeaux mixture, mix together copper sulfate and hydrated lime in water. The typical ratio is 4 parts copper sulfate to 4 parts hydrated lime to 100 parts water. Ensure everything is fully dissolved before using it as a fungicide in the garden.
What does ppm mean?
ppm is an abbreviation for 'parts per million'.
How do I convert 10 percent CO2 to parts per million CO2?
-- Take the number of percent. -- Multiply it by 10,000-- The answer is the number of parts per million. . 10 percent = 100,000 parts per million.
What percent of the element barium found on earth?
The abundance of barium is 456 parts per million (numbers of atoms). That is 0.05 per cent, approx.

What is the name of BaCl2.2H2O?
Barium Dichloride is NOT correct. The name is Barium Chloride it is a binary ionic compound.
How much is 10 parts per million?
If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
Can you use copper sulfate in your pool and how much?
Yes, copper sulfate can be used in pools as an algaecide to control algae growth. The recommended dosage for copper sulfate in pools is usually 0.2-0.4 ppm (parts per million), but it's important to carefully follow the manufacturer's instructions for the specific product you are using. Overuse of copper sulfate can lead to staining of pool surfaces and hair discoloration.
What the sulphate limit in soil after then use sulphate resistant cement?
The sulfate limit in soil after using sulfate-resistant cement is typically around 2,000 parts per million (ppm). Sulfate-resistant cement is designed to withstand sulfate attack in soil, reducing the risk of deterioration due to sulfates. Monitoring sulfate levels in the soil after construction is important to ensure that the limit is not exceeded, as high sulfate levels can compromise the durability of the structure.
How do you compare solubility between substances?
Solubility can be written as %m/m (mass in g per 100g), %m/v (mass in g per 100mL), %v/v (mL per 100mL), ppm (parts per million), ppb (parts per billion) etc. Solubility is also dependant on pressure and temperature. Due to these variables, in the same units (eg. %m/m) and at the same set of temperature and pressure (SLC or STP) you can compare the solubility values.
What is solubility of chromium?
If At 25 Degrees C, the molar solubility of barium chromate in water is 1.1 x 10^-5 M. Here is how you would find the solubility in grams per liter.First: You must know the molar mass of Barium Chromate To continue. Look at your periodic Table.[BariumChromate Molar mass=253.37 g/mol]*Get this by adding together atomic number of each element in BaCrO4*253.37= Ba+Cr+O(4), or 137.33+52+16(4)*Take 1.1 x 10^-5 M and divide by molar mass of Barium Chromate1.1 x 10^-5 mol/L x 253.37 =0.002787Answer in grams per liter to three significant figures=2.787 x 10^-3 g/LHow many liters of water are required to dissolve 1 of barium chromate?*take 1gram BaCrO4 / 2.787 x 10^-3 g/L --------> Grams Cancel=2.787 x 10^-3 LAnswer in liters to three significant figures =359.71 LitersWhat is the solubility of barium chromate in parts per million?*parts per million = Grams of Solute/grams of solution X 10^6 (which is ppm)2.787 x 10^-3g/L x 1L/1000g x 10^6 = 0.02779, or 2.78 x 10^-2ppmAnswer in parts per million to three significant figures=2.78ppm**For dilute aqueous solutions, ppm is equivalent to units of mg/l
What is the abbreviation for parts per million?
parts per million = ppm
What does the word 'sulfate' suggest about a chemical with that in its name?
There are two parts to this question:1) What is a sulfate? -- A sulfate is any molecule that has the ion SO42- in it. That ion is called "sulfate".2) What chemical properties are conferred on sulfates? -- There are no consistent properties across all sulfates, and many more relevant properties derive from the atom paired with the sulfate in an ionic compound. That being said, most sulfates will dissolve easily in water, especially sulfiric acid (H2SO4) which is a strong acid. However, the most commonly used sulfates, like gypsum and barium sulfate are not actually very soluable. Sulfates can often serve as ligands in certain instances.
What is the solubility of nitrogen in water?
Nitrogen is not very soluble in water, with a solubility of approximately 0.015 grams per 100 grams of water at room temperature. This low solubility is due to nitrogen being a nonpolar molecule, which does not readily interact with the polar water molecules.
