How do you define minimum effective concentration?
Minimum effective concentration refers to the lowest concentration of a substance required to achieve a desired effect or therapeutic outcome. It is the minimal dose necessary for a drug or compound to produce a specific response in the body. Below this concentration, the substance may not be effective.
A solution contains 2.0 x10-5 m K3PO4 what is the minimum concentration of AgNO3 that would cause precipitation of solid Ag3PO4 ksp1.8 x10-18?
To determine the minimum concentration of AgNO3 needed for precipitation to occur, calculate the concentration of Ag+ ions in solution first. Since Ag3PO4 has a 3:1 stoichiometry with Ag+, this value is equivalent to the solubility product constant (Ksp) of Ag3PO4. Using the Ksp value and the concentration of PO4^3- ions from the K3PO4, you can calculate the minimum Ag+ ion concentration needed by dividing Ksp by the concentration of PO4^3-. This concentration represents the minimum AgNO3 concentration required for precipitation to begin.
What is the minimum time an iodine sanitizer solution must be in contact with the object being sanitized?
The minimum contact time for an iodine sanitizer solution to effectively sanitize objects is typically around 1 minute. It is important to follow the manufacturer's guidelines for proper dilution and contact time to ensure effective sanitization.
What's the difference between isotonicity and isoosmosis?
Isotonicity refers to a solution having the same osmotic pressure as another solution, resulting in no net movement of water across a semi-permeable membrane. Isoosmosis, on the other hand, refers to the equal movement of solvent molecules in opposite directions across a semi-permeable membrane, leading to no change in concentration on either side. In summary, isotonicity relates to solute concentration and osmotic pressure, while isoosmosis involves the movement of solvent molecules.
What is the minimum volume of a 2.81 m naoh solution needed to make 150.0 ml of a 0.800 Mnaoh solution?
To find the minimum volume of the 2.81 M NaOH solution needed, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (2.81 M), V1 is the volume of the initial solution, C2 is the final concentration (0.800 M), and V2 is the final volume (150.0 ml). Rearrange the formula to solve for V1. V1 = (C2V2) / C1 = (0.800 M * 150.0 ml) / 2.81 M = 42.72 ml. Therefore, the minimum volume of the 2.81 M NaOH solution needed is 42.72 ml.

Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left?
The minimum concentration of the precipitating agent required to cause precipitation of the cation in solution will depend on the solubility product constant (Ksp) of the cation's salt. The concentration of the precipitating agent must be sufficient to exceed the solubility product constant and drive the reaction towards precipitation. To determine the exact concentration needed, you would need to know the Ksp value for the cation's salt.
What is the difference between MIC and MBC?
MIC - Minimum Inhibitory Concentration is the lowest concentration of an antibiotic needed to stop the microbe from reproducing.MBC - Minimum Biocidal Concentration is the lowest concentration of an antibiotic needed to kill the microbe.

What is taste threshold?
Taste threshold is the minimum concentration of a substance needed for a person to detect a taste. It varies depending on the individual's sensitivity to flavors and can be influenced by factors such as age, genetics, and health conditions.
What should the minimum percent of Isopropyl Alcohol be to prevent contamination of an IV?
The minimum recommended concentration of Isopropyl Alcohol to prevent contamination of an IV site is typically 70%. Below this concentration, it may not effectively kill bacteria and other microorganisms. Therefore, it is important to use a solution that contains at least 70% Isopropyl Alcohol to ensure proper disinfection.
Between potassium nitrate and aluminium nitrate which one is required in minimum concentration to coagulate arsenious sulphide sol?
Aluminium nitrate is required in minimum concentration to coagulate arsenious sulphide sol. This is because aluminium ions have higher charge density compared to potassium ions, allowing for more effective coagulation of the negatively charged arsenious sulphide particles.
What minimum concentration of alcohol in the blood is usually fatal?
legally drunk
