Explain why a 0.10 HCL solution is assumed to have a pH value 1?
HCl is a strong acid. Therefore, it can be expected to fully dissociate in aqueous solution, yielding one hydrogen ion and one chloride ion per molecule. The concentration of the hydrogen ion should thus be the same as the initial concentration of the HCl. Therefore, a 0.10M HCl solution has an H+ concentration of 0.10M. By the equation pH=-log[H+], the pH of this solution is 1.
Explain what happens when sodium hydroxide solution is added to ammonium hydroxide?
No reaction takes place. pH of the solution increase.
Identify and explain the relationship between the mole concept and solution concentration?
ahm... im really not so sure about this thing... but i think that, the more number of moles present in a solution the more concentrated it is....
Based on Arrhenius theory explain why CaCl2 can be considered a neutral solution rather than an acidic solution or basic solution?
It's. Neutral solution cause the solution didn't create a hydrogen ion nor a hydroxide ion making it neutral
Explain why the temperature of water might increase when a solution forms?
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a liquid solvent to form a homogeneous solution. The solubility of a substance strongly depends on the used solvent as well as on temperature and pressure. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration where adding more solute does not increase the concentration of the solution. The solvent is generally a liquid, which can be a pure substance or a mixture.[1] One also speaks of solid solution, but rarely of solution in a gas (see vapor-liquid equilibrium instead) The extent of solubility ranges widely, from infinitely soluble (fully miscible[2] ) such as ethanol in water, to poorly soluble, such as silver chloride in water. The term insoluble is often applied to poorly or very poorly soluble compounds.

What solution has a greater concentration of hydrogen ions a solution with a pH of 3 of a pH of 5 Explain?
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.
Can you tell which solution has higher sugar concentration Explain?
Depending on the solute... (not sure though) but y

How does osmosis explain the movement of water across cell membranes?
Osmosis is the movement of water from a solution of high concentration to a solution of lower concentration through a membrane. Water passes through the membrane, diluting the solution of higher concentration on the other side, until both solutions on either side of the membrane have equal concentrations.
How do I explain this hypothesis 'The higher the amount of calcium hydroxide added the more the pH will increase'?
Calcium hydroxide has a low solubility in water yet if the concentration of hydroxyl ions increase the pH increase.
Explain why it is not enough just to say that a solution is hypertonic?
hypertonic and hypotonic are relative terms. A solution that is hypertonic to tap H2O could be hypotonic to seawater. In using these terms, you must provide a comparison, as in 'the solution is hypertonic to the cells cytoplasm'.

What is the formula for molarity and explain each part?
molarity (M) is the concentration of moles (n) of a solute per liters (v) of solution M=n/v
What is solution space explain?
There is no solution.
