Most of the time it iis used to protect the formation (which may be friable shale or the like) from damage caused by fresh water leaching the minerals, such as, calcium, magnesium, etc, from the clay or shales downhole. Potassium ion is especially effective at preventing this due to its high solubility and large ionic size. Being abundant and low cost also helps.
What else can I help you with?
Is 20 percent NEFE acid heavier than 2 percent KCL water?
Yes, a 20 percent NEFE acid solution is heavier than a 2 percent KCL water solution because the density of NEFE acid is higher than that of KCL water. The higher concentration of NEFE acid contributes to its increased weight compared to the lower concentration of KCL in water.
When 200 mL of water are added to 100mL of 12 percent KCL solution the final concentration of KCL is?
The initial amount of KCl in the solution is 12mL (12% of 100mL). When 200mL of water is added, the total volume becomes 300mL. You would then divide the initial amount of KCl (12mL) by the total volume (300mL) and multiply by 100 to get the final concentration of KCl in the solution.
Is KCl insoluble?
No. Potassium chloride (KCl) is soluble in water.
How many ppm is 2 percent KCl?
2 percent KCl is equivalent to 20,000 parts per million (ppm) because 1 percent = 10,000 ppm.
Using water how can i distinguish KCl from PbCl2?
KCl is soluble in water, so when added to water it will dissolve easily. PbCl2, on the other hand, is insoluble in water and will form a white precipitate. By observing whether the compound dissolves or forms a precipitate in water, you can distinguish between KCl and PbCl2.
Is 20 percent NEFE acid heavier than 2 percent KCL water?
Yes, a 20 percent NEFE acid solution is heavier than a 2 percent KCL water solution because the density of NEFE acid is higher than that of KCL water. The higher concentration of NEFE acid contributes to its increased weight compared to the lower concentration of KCL in water.

Is KCl insoluble?
No. Potassium chloride (KCl) is soluble in water.
Is KCl soluble or insoluble?
KCl is highly soluble in water and some other solvents.
How many ppm is 2 percent KCl?
2 percent KCl is equivalent to 20,000 parts per million (ppm) because 1 percent = 10,000 ppm.

Is KCl a solute or a solvent?
Potassium chloride does form an aqueous solution when dissolved in water.
What is the Empirical formula of the compound that is 52.7 percent K 47.3 percent Cl?
The empirical formula of the compound with 52.7% K and 47.3% Cl is KCl (potassium chloride). This is because the ratio of potassium to chlorine atoms in the compound is 1:1, leading to the simple formula KCl.
What color is KCl in water?
the solution of KCl looks like a clear water with little tint of gray swirls
What if a potassium chlorate sample is contaminated with KCL would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
If a potassium chlorate sample is contaminated with KCl, the experimental percent oxygen would be lower than the theoretical percent oxygen. This is because KCl does not contain oxygen, so the contamination would dilute the amount of oxygen produced during the decomposition of potassium chlorate.
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
How many grams of kcl can dissolve in 100g of water at 30C?
Approximately 34 grams of KCl can dissolve in 100g of water at 30°C.
