What is the pH of strontium?
Strontium does not have a pH as it is not an acid or base in itself. However, it will react with water to produce strontium hydroxide, which is a base and will produce a pH greater than 7. pH is not a measure of how strong an acid or base is, it is a measure of how acidic or basic a solution is. It depends on both how strong a dissolved acid or base is and how much is dissolved in a given volume of water.
Why is solubility not necessarily related to the strength of a base?
Solubility and the strength of a base are distinct concepts; solubility refers to how much of a substance can dissolve in a solvent, while base strength measures the degree to which a base can accept protons or donate hydroxide ions in solution. A strong base, like sodium hydroxide, is highly soluble and dissociates completely in water. Conversely, some strong bases, such as barium hydroxide, may be less soluble, while weak bases can be more soluble yet only partially ionize. Therefore, the solubility of a base does not directly correlate with its ability to increase hydroxide ion concentration in solution.
How do you calculate drugs and solution?
To calculate drug dosage in a solution, you need to know the concentration of the drug in the solution (in mg/mL or other units) and the desired dose in mg. You can then use the formula: (Dose needed / Concentration of drug) = Volume of solution to be administered. This will help you determine how much of the solution to give to achieve the desired dose.
What kind of solution would have Kb value that is much greater than 1?
A solution with a Kb value much greater than 1 indicates that it is a strong base, as Kb represents the base dissociation constant. In such solutions, the base dissociates significantly in water, producing a high concentration of hydroxide ions (OH⁻). Examples include strong bases like sodium hydroxide (NaOH) and potassium hydroxide (KOH), which completely ionize in solution.
What happensif you use twice as much solvent?
If you use twice as much solvent, the concentration of the solute in the solution will decrease. This could affect the reactivity of the solute, the solubility of the solute, and the overall properties of the solution. Additionally, the volume of the solution will increase, leading to changes in factors like viscosity, boiling point, and freezing point.
Given a 5 Molar sodium hydroxide Calculate how much 5 Molar base you need to make a 100 mL of a 1 M solution?
20 ml
A base that only partly ionizes in a solution is what kind of base?
A base that only partly ionizes in a solution is considered a weak base. This means that only a small fraction of the base molecules will ionize to release hydroxide ions in the solution. Examples of weak bases include ammonia (NH3) and methylamine (CH3NH2).
What is a concentrated base?
Technically, a concentrated base is any high molar solution of any number of proton acceptors that, when dissolved, result in an increase in pH. Commonly, concentrated base is a high molar solution of sodium hydroxide; typically referred to as lye.
How much salt must be added to 60kg of a 20 percent solution of salt to increase it to 40 percent solution of salt?
20%

It depends on both how strong a dissolved acid or base is and how much is dissolved in a given volume of water.
What is a strength of a base?
The strength of a base is how much it dissociates in water.
What solution will have a Kb value that is much greater than 1?
a strongly basic solution
What is the buffer capacity formula and how is it used to calculate the ability of a solution to resist changes in pH?
The buffer capacity formula is defined as C/pH, where represents the buffer capacity, C is the change in concentration of the acid or base in the solution, and pH is the resulting change in pH. This formula is used to quantify the ability of a solution to resist changes in pH by measuring how much the concentration of the acid or base in the solution can change without significantly altering the pH. A higher buffer capacity indicates a greater ability of the solution to maintain a stable pH level when acids or bases are added.
How much greater a base is a solution with a pH of 11 than 8?
The factor of multiplication is 1000.

What kind of solution would have a Kb value that is much greater then 1?
A solution with a Kb value much greater than 1 would be considered a strong base solution. This indicates that the base is more likely to fully dissociate in water, resulting in a high concentration of hydroxide ions and a higher pH. Examples include solutions of sodium hydroxide (NaOH) or potassium hydroxide (KOH).
