A 250 ml sample of saturated a g o h solution was titrated with h c l , and the endpoint was reached after 2. 60 ml of 0. 0136 m h c l was dispensed. Based on this titration, what is the k s p of a g o h <u>. Ksp=1.9×10⁻⁸</u>
<h3>What is titration?</h3>
Titration is a typical laboratory technique for quantitative chemical analysis used to calculate the concentration of a specified analyte. It is also referred to as titrimetry and volumetric analysis (a substance to be analyzed). A standard solution with a known concentration and volume is prepared as the reagent, also known as the titrant or titrator. To ascertain the concentration of the analyte, the titrant reacts with an analyte solution (also known as the titrand). The titration volume is the amount of titrant that interacted with the analyte.
A typical titration starts with a beaker or Erlenmeyer flask being placed below a calibrated burette or chemical pipetting syringe that contains the titrant and a little amount of the indicator (such as phenolphthalein).

Answer:
An ionic bond is the electrostatic force that holds ions together when they form bonds
Explanation:
An ionic bond is formed when a metal looses electron(s) to a non metal leading to the formation of a positive ion and a negative ion.
An ionic compound is actually an ion pair, the ions are held together by strong electrostatic forces.
This strong electrostatic force that holds the ion pair together in ionic compounds is what we commonly call the IONIC BOND.

Answer:
Diffusion occurs in solid and liquid through the constant and random motion of the smaller particles called molecules of either solid, liquid or gaseous in permeable medium as witnessed in the experiment.
Explanation:
The kinectic molecular theory of matter states that the smaller particles of matters called molecules are in constant, but random motion and the degree of movement of the molecules depends on the state or phase such matter exist, which is a derivative of the total kinetic energy possessed by the molecules. This average kinetic energy of the molecules as iodine for example is proportional to the temperature of the matter.
Diffusion should be remembered as the movement of molecules of matters from a highly concentrated region otherwise called hypertonic region to a less concentrated region called hypotonic region through a permeable medium until there is an equilibrium in the system. Since diffusion is expected to involve the movement of molecules, and any matter that can exhibit diffusion is said to have moving molecules, therefore, the kinetic molecular theory of matter is proven to be accurate with the observed movement of iodine molecules in the test tube. This shows that even the molecules of solid matters are in constant random motion, this is made more convincing when these molecules migrate without the addition of external energy source like heat, which then help to understand that the natural iodine molecules are in constant random motion, as they are changed to gaseous state without passing through liquid state, a phenomenon called sublimation.
