PPT-Lecture 2 - Major Ions in Sea Water

Why do we care about the major ions What is the composition of seawater What defines Major Ions What are their concentrations What are their properties Density distributions and controls salinity and temperature. the key is that the electrons of each covalent bond are not shared equally between oxygen and hydrogen atoms. . Oxygen pulls electrons much more strongly than does hydrogen. . This sharing of electrons causes the oxygen end of the molecule to have a slight negative charge,. Collin College. Lecture Presentation. Chapter . 4-3. Chemical Quantities and. Aqueous Reactions. Binary Acids. Acids are molecular compounds that . ionize. when they dissolve in water.. The molecules are pulled apart by their attraction for . Electrolytes and pH. Electrolyte. Electrolyte: a substance that when dissolved in water allows an electric current to flow through the solution. Example: table salt. Some substances can be dissolved in water but do not conduct electricity called . Chapter 4. Reactions in Aqueous Solution. James F. Kirby. Quinnipiac University. Hamden, CT. Solutions. Solutions. are defined as homogeneous mixtures of two or more pure substances.. The . solvent. However differences become obvious when we use soap to wash. In certain places when we wash with soap, the water forms a rich lather easily, but others it is more reluctant to – this is because the water is HARD. . Just remember…. CHEMISTRY IS GREAT!!!. I will email you a copy of this. So don’t copy notes for the sake of it! Just write down any extra bits you want. This is you!. C3. MENDELEEV:. Arranged by atomic mass. What are the four emergent properties of water that are important for life?. cohesion, expansion upon freezing, high heat of evaporation, capillarity. cohesion, moderation of temperature, . expansion upon freezing, solvent properties.

Artists did not have an affordable, stable blue pigment until 1704, when a paint maker accidentally produced Prussian blue in his laboratory. . The pigment quickly became extremely popular due to its deep color and because it faded in light much less than other blue pigments; it has since been used by countless artists, including van Gogh and Picasso. .
