What is resorcinol solution?
Dilute water solutions of resorcin (dihydroxybenzene) are used as antiseptic, disinfectants and as components in drugs for dermathology treatments.
Explain why dilute silver nitrate must be used when applied to the eyes rather than concentrated?
Dilute silver nitrate is used when applied to the eyes because concentrated silver nitrate can be highly caustic and can cause severe damage to the delicate tissues of the eye. Diluting it reduces its potency and lowers the risk of harm. Additionally, dilute solutions are better tolerated by the eye, making them safer to use for certain medical procedures or treatments.
Why are standard solutions used?
A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
What are the Tonicity of the cell?
Cells can be placed in solutions with higher, lower, or equal concentration to the cell... 1. ISOTONIC: - a solution with equal concentration to the cell. - 0.9% NaCl solutions is isotonic to RBC (red blood cells). - isotonic solutions cause no net gain or loss of water to a cell. 2. HYPOTONIC: - solute concentration is greater on the inside of the cell (or: the outer solution has less concentration than inside). - >0.9% NaCl solutions is hypotonic to RBC (red blood cells). - causes swelling, could burst (lyse) - net gain of water 3. HYPERTONIC: - <0.9% NaCl solutions is hypertonic to RBC (red blood cells). - net loss of water from the cell. - solute concentration is greater on the outside of the cell (or: the outer solution is greater concentration than the inside). - causes the cell shrink (crenation in RBC)
Why are isotonic solutions used as parenteral solutions?
this is because isotonic solutions are fluids that contains the same concentration of solutes as plasma in human..(*_*) that's what i think..._pinkay

Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
Measurement system used to indicate the concentration of hydrogen ions in solution?
ph scale
Why can color be used only for comparing similar solutions and not comparing different solutions?
Concentration. If the color is dark then its more concentrated and lighter means less

Why is a concentrated acid not strong?
strong acids and bases dissociate completely; weak acids and bases dissociate only partially. In contrast, the term dilute and concentrated are used to indicate the consentration of a solution, which is the amount of acid or base dissolved in the solution. It is possible to have dilute solutions of strong acids and bases and concentrated solutions of weak acids and bases.
What is blood alcohol concentration?
The blood alcohol concentration is a measurement of how much alcohol is mixed in with your blood. This formula is used to determine if you have consumed too much to be driving.
Can you dilute water?
Water is the most common liquid used to dilute solutions (reduce their strength). Adding anything to water will not change its properties, only introduce other chemical properties. That is, if you added alcohol to water, you would be diluting the alcohol, not the water. You can moderate some of the properties of water by heating or cooling it, or adding solid solutes to make a gel or suspension.

What is the measurement system called that indicate the concentration of H ions in solution?
The pH system is used to indicate the concentration of hydronium ('H+') ions in solution. It is governed by the equation pH = -log[H+]
What is the advantage of potentiometry?
Potentiometry is a field of electroanalytical chemistry in which the potential of a solution is measured with no current flow; there are many different methods of doing this and structures of potentiometers in existence. It is used to determine the concentration of different analyte ions in solution. This can have many practical applications; potentiometry is used to determine the end-point of titrations, the amount of fluoride in drinking water, and the pH of solutions, among many other things.
