(DDS LAB) Exp 3: Calcium Hydroxide Topical Solution

What are the 3 main categories of preparation of solutions?

1. -

2. -

3. -

Simple solution
Solution by reaction
Solution by extraction

The preparation is made through the ________________ method as it only involves dissolving the solute in the solvent

simple solution

___________________ is defined as the ability of the solvent to dissolve organic/inorganic solutes by overcoming the forces that hold the atoms of the solute together and uniformly mix the molecules of the solute and solvent together and form new forces of attraction

Solubility

What are the factors that affect the solubility of a given solute in a solvent?

1. -

2. -

3. -

4. -

5. -

physico-chemical properties of the solute
temperature
pressure
acidity/basicity of the solution
physical agitation

_____________________ is used as an astringent in topical preparations in which it is incorporated along with other ingredients to act as an emulsifying agent

Calcium Hydroxide Topical Solution

Calcium hydroxide topical solution is a solution containing, in each 100 mL, not less than _______ mg of Calcium hydroxide

140

___________________ is a solution in which water is the solvent. In this preparation, the solvent used to dissolve calcium hydroxide is water

aqueous solution

________________________ is a solution containing the maximum amount of solute that can dissolve in a solvent at a specified temperature and pressure, with excess undissolved solute present at equiplibrium

saturated solution

_________ - less than 1
_________ - from 1 to 10
_________ - from 10 to 30
_____________ - from 30 to 100
______________ - from 100 to 1000
______________ - from 1000 to 10,000
_____________________ 10,000 and over

very soluble
freely soluble
soluble
sparingly soluble
slightly soluble
very slightly soluble
practically insoluble or insoluble

___________________ are properties such as surface area, particle size, and crystal form can affect its interaction with the solvent and its solubility

physico-chemical properties of the solute

__________________ affects solubility depending on the substance. For this solubility decreases as the temperature increases, thus the use of cool purified water

temperature

___________________ affects the solubility of gases and has little effect on solid calcium hydroxide

pressure

__________________ can affect the solubility of ionizable substances by changing their degree of ionization

acidity/basicity

___________________ increases contact between the solute and solvent and mainly increases the rate of dissolution rather than the final equilibrium solubility

physical agitation
