Solution
A solution is a homogeneous mixture of a solute dissolved into a solvent. Solute- A solute is a dissolved substance solvent- A solvent is the most abundant component of a solution, it does the dissolving Aqueous- The "universla solvent" is water because waster is the solvent it dissolves in many substances
Factors that affect solubility temperature - sold sustenance has higher solubility as the temperature increases gases have lower solubility as temperature increases. pressure - only affects gas solutes gases solutes have higher solubility as pressure increases
liquid solutions
concentration: indicates the amount of solute dissolved in a given quantity of solute Dilute- a small amount of solute concentrated: a large amount of solute
Liquids that dissolve in one another in all proportions are said to be miscible. Liquids that do not dissolve in one another are deemed immiscible. The general rule for deciding if one substance is capable of dissolving another is "like dissolves like".
Moarity
the most important unit of concentration is the molarity Molarity: (M) is the number of moles of solute dissolved in one liter of solution important note: the volume is the total volume of the resulting solution, not the solvent alone. example: what is the molarity of a solution that contains 0.25 moles of NaCI in 9.75l of the solution? M= Mol= 0.25 mol NaCl m=0.25mol/ 0.75L L=0.75L morlarity= 0.33mol or 0.33m
Acids
Acids are solutions that have H+ ions as the cation ( positivity chartered atoms) characteristics of acids are that they taste sour, and have less than 7. When litmus tests are done, the paper is red and pink
Bases
bases are solutions that have OH ( hydroxide) as the anion (negatively charged atoms or -H+ acceptors. Some characteristics are cleaning products, taste bitters, and Ph greater than 7. Litmus test paper turns blue.

pH scales: the measure of the acidity of a solution PoH- the measure of alkalinit of a solition
Ph=-log [H+] exmaple: what is the Ph of a solution that has an [ H+] = 1.5x 10M PH= -log [1.5 x 10^-4] Ph= 3.8
[h +] =10^-ph Exmaple: what is the [H+] in a solution with Ph=9.42 9.42= -log[ H+] -9.42= log [H+]
Ph+PoH= 14 Exaomple- what is the Ph in a solution with a pOH= 8.6 14-8.6=5.4
[ H+] [OH]= 1.0 x 10^-14m exmaple- what is the [H+] [6.73x 10^-5]= 1.0x 10^-14 [H+]=1.49 x 10^-10m
