Concentration is the measure of how much of a given substrate is mixed with another substance,so it can never be negative.
Not necessarily. Although saturation means that the solution cannot get concentrated anymore, it does not mean that the concentration is high, as there might be solutions that a saturated at low concentrations.
No, molarity cannot be negative because it is a measure of the concentration of a solute in a solution and is always expressed as a positive value.
The reference solution in a chemistry lab is the solution that is always present in the experiment, and it doesn't go away while you are testing other solutions. It is kind of like a base camp for your experiment; you're always starting off or going to include it.
It does not matter whether or not HCl is dilute because either way it's a strong acid. Strong and weak are based on its percentage of ionization whereas diluting affects the concentration of the ions. A dilute solution of HCl is not weak.
Yes, water will always move from a hypertonic solution (higher solute concentration) to a hypotonic solution (lower solute concentration) in an attempt to equalize the solute concentration on both sides of the membrane. This process is known as osmosis.
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
Concentration is the measure of how much of a given substrate is mixed with another substance,so it can never be negative.
In a titration, the moles of the titrant added are equal to the moles of the analyte in the solution at the endpoint. This equality is essential for determining the concentration of the analyte in the solution.
Not necessarily. Although saturation means that the solution cannot get concentrated anymore, it does not mean that the concentration is high, as there might be solutions that a saturated at low concentrations.
it is very easy to prepare working solution from a stock solution we use the formula for this purpose which is: C1V1 = C2V2 C1 is the concentration of the stock solution V1 required volume from the stock solution C2 concentration of the working solution V2 volume of the working solution
Saline solution should always be in given as a concentration of 0.9% sodium chloride (NaCl).
Two parts, a solvent and a solute. The solute will be a stable compound with a known concentration.
On a 1 ml syringe, 2.5 mg would depend on the concentration of the solution being measured. If you know the concentration (for example, if it’s 1 mg/ml), 2.5 mg would be indicated at the 2.5 mark on the syringe, which is halfway between the 2 ml and 3 ml marks. Always ensure you confirm the concentration of the medication to ensure accurate dosing.
The sum of pH and pOH is always equal to 14 in a neutral solution at 25°C. This is because pH is a measure of the concentration of H+ ions in a solution while pOH is a measure of the concentration of OH- ions. In a neutral solution, the concentration of H+ ions is equal to the concentration of OH- ions, resulting in a sum of 14.
In an aqueous solution the solvent is water.
No, molarity cannot be negative because it is a measure of the concentration of a solute in a solution and is always expressed as a positive value.
