Equations and Inequalities

We’ll show some examples so that you can see the operations we can do with inequalities just as with equations. We will first examine the pattern that takes place when we perform a given operation on both sides of an inequality.

The acetate ion, CH3CO2 −, is the conjugate base of acetic acid, CH 3 CO 2 H, and so its base ionization (or base hydrolysis) reaction is represented by. CH3CO2 − (aq) + H2O(l) ⇌ CH3CO2H(aq) + OH − (aq) Kb = Kw/Ka. Because acetic acid is a weak acid, its Ka is measurable and Kb > 0 (acetate ion is a weak base).

Sodium chloride - Wikipedia

Sodium chloride /ˌsoʊdiəm ˈklɔːraɪd/, commonly known as salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. In its edible form of table salt…

Experiment # 9: The Henderson-Hasselbalch Equation

conjugate base (or salt). A comparable equation is obtained for a buffer solution consisting of a mixture of a weak base and its salt, namely: pOH = pKb + log ([Salt]/[Base]). Solutions of a weak acid and its salt (conjugate base) may be obtained by mixing an excess of weak acid with some strong base to produce the salt by partial neutralization.

Acid Rain - Department of Chemistry

Sulfuric acid is a strong acid, so it readily dissociates in water, to give an H + ion and an HSO 4-ion (Equation 7). The HSO 4-ion may further dissociate to give H + and SO 4 2-(Equation 8). Thus, the presence of H 2 SO 4 causes the concentration of H + ions to increase dramatically, and so the pH of the rainwater drops to harmful levels.

Alum - Wikipedia

An alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO 4) 2 ·12H 2 O, where X is a monovalent ion such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2 ·12H 2 O.Other alums are named after the monovalent ion, such as sodium alum and ammonium alum.

A salt bridge keeps charges from accumulating on one side or the other, thus maintaining charge neutrality. If the external circuit is open so electrons cannot flow freely through it, electrons pile up on the left-hand side of the broken circuit and are depleted on the right-hand side, which results in the potential difference or cell potential (measured in volts).
