In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchangingelectronsbe...
One example of an Arrhenius base is sodium hydroxide (NaOH): NaOH ⇔ Na+ + OH- Bases typically have "OH" in their formulas, though there are exceptions. For example, ammonia (NH3) doesn't contain hydroxide ions but forms them when it reacts with water: NH3 + H2O ⇔ NH4+ + OH-...

What Is pH? pH is a measure of the acidity or basicity of a solution. The acidity or basicity of any solution is defined by its concentration of protons. So, mathematically, pH is the negative log to base 10 of the proton concentration. In chemistry, the concentration of any species ...
what molarity of HCl is "dangerous" «on:May 15, 2005, 06:37:12 PM » Hey there. First-time poster, long-time chemistry fan. We did a simple acid-base titration in class, with a solution of 0.10 mol/L NaOH, and a solution of HCl of unknown concentration. Through calculations of...
Combining hydrochloric acid (HCl) and sodium hydroxide (NaOH) Classification of Mixtures Mixtures may be categorized as either homogeneous or heterogeneous. Ahomogeneousmixture has a uniform composition that doesn't readily separate. Every part of a homogeneous mixture has the same properties. In a ho...
