sodium hydroxide

Sodium hydroxide, also known as caustic soda,[2][3] or lye, is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid, and is a highly caustic metallic base and alkali salt. It is available in pellets, flakes, granules, and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water, ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries...

Antacids: Calcium Carbonate and Magnesium Compounds

rebound", a condition whereby the gastric acid returns in greater concentration after the drug effect has ceased. Moreover, this class of antacids is not suitable for all patients owing to its components. For example, the usually high concentration of sodium bicarbonate present in these chemical antacids may be inappropriate for patients afflicted with hypertension or kidney failure. Non Absorbable Antacids The non-absorbable antacids though less prone to cause a rebound effect, have their fair...

Alkali Metals

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table, viz. Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell, which is just outside an inert...

Neutralization Titrations: The Determination of Soda Ash

Neutralization Titrations: The Determination of Sodium Carbonate from Unknown Soda Ash Unknown # I. Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH, HCl vs the known NaOH, and the unknown Soda Ash sample vs the known HCl. II. Equations and Sample Calculations: Titration of HCl with NaOH: Complete Equation: HCl (aq) + NaOH (aq) ...

Sodium Intake

Sodium is a mineral that is present only in small quantities in most natural foods, but salt is added, often in large amounts, in food processing and by cooks to enhance flavor. Sodium is the predominant ion in extra cellular fluid. Sodium (Na) is the predominant cation in extra cellular fluid and its concentration is under tight homeostatic control. Excess dietary sodium is excreted in the urine. The kidney very efficiently reabsorbs the mineral when intakes are low or losses are excessive. Sodium...

Controlled Assessment-Thermal Decompostion of Metal Carbonate Linked with Reactvity Series

investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So...
