CHAPTER 15 Aiase Tit ration an H

Recall that strong acids and bases are considered completely ionized or dissociated in weak aqueous solutions A review of strong acids and bases is given in Figure 1 4 Because NaOH is a strong base 1 mol of it will yield 1 mol of OH-in an aqueous solution NaOH(s) ―

It is very alkaline and is a strong base along with sodium hydroxide lithium hydroxide calcium hydroxide barium hydroxide and strontium hydroxide Properties Pure potassium hydroxide is a colorless highly hygroscopic solid crystalline compound having density of about 2 04 g/cm 3 readily soluble in water (1 g KOH dissolves in 0 5 g water) and lower alcohols (methanol ethanol

water it forms calcium carbonate (CaCO3) which is slightly soluble in water making it milky A — NaHCO3 B — Na2CO3 C — CO2 gas 39 In one of the industrial processes used for manufacture of sodium hydroxide a gas X is formed as by product The gas X reacts with lime water to give a compound Y which is used as a bleaching agent in chemical industry Identify X and Y giving the

Likewise a strong base produces a relatively weak conjugate acid THE STRONG ACIDS AND BASES There are only a few strong acids and bases which are listed below: Strong Acids Hydrobromic acid (HBr) Hydrochloric acid (HCl) Hydroiodic acid (HI) Nitric acid (HNO 3) Perchloric acid (HClO 4) Sulfuric acid (H 2 SO 4) Strong Bases Barium hydroxide (Ba[OH] 2) Calcium hydroxide (Ca[OH] 2) Lithium

ACIDS BASES AND SALTS

Strong acid and weak base combine to form acidic salt For Example Hydrochloric Acid and ammonium hydroxide combine to form ammonium chloride Other examples sodium hydrogen carbonate sodium hydrogen sulfate etc HCl + NH 4 OH → NH 4 Cl + H 2 O Eq 2 Formation of Acidic Salt Similarly weak acid and strong base combine to form basic salt

Strong bases: any very soluble hydroxide can be considered a strong base so any first-column hydroxide (LiOH NaOH KOH etc) The second-column hydroxides are usually soluble enough to be considered strong (magnesium hydroxide calcium hydroxide barium hydroxide) but I don't expect to make any fine distinctions on those if I want to use a strong base on the exam it will be either NaOH

Images Practice Strongly alkaline sodium hydroxide is formed in solution Sodium metal reacting vigorously with water (with filter paper on top to restrict its movement) So much heat is liberated that hydrogen formed ignites together with sodium vapor Intense golden yellow flame color is characteristic of sodium its salts Potassium metal reacting violently with water So much heat is

For reference Figure Figure5 5 shows BGA results after mixing equimolar 1:1 base-treatment solutions which contain equal proportions of the weak base NaHCO 3 to the strong base Na 2 CO 3 but different total carbonate species concentrations with HCl-CA-K9-2 (9 parts acidified blood: 1 part base solution) Reference values of the BGA parameters of the acidified canine blood in the absence of

Calcium Hydroxyapatite Based Sulfonate Grease

An overbased calcium sulfonate grease composition comprising a reduced amount of overbased calcium sulfonate calcium hydroxyapatite base oil one or more converting agents and one or more complexing acids if a complex grease is desired The calcium sulfonate grease composition improves thickener yield and expected high temperature utility as demonstrated

Calcium Analysis by EDTA Titration One of the factors that establish the quality of a water supply is its degree of hardness The hardness of water is defined in terms of its content of calcium and magnesium ions Since an analysis does not distinguish between Ca2+ and Mg2+ and since most hardness is caused by carbonate deposits in the earth hardness is usually reported as total parts per

weak strong pH7 strong weak pH7 weak weak depends on which is stronger Using neutralisation:- 1 Farmers use quick lime (calcium oxide) to neutralise acid soils 2 Our stomach contains hydrochloric acid and too much of this causes indigestion Antacid tablets contain bases such as magnesium hydroxide and magnesium carbonate to neutralise

Calcium hydroxide still counts as a strong base because of that ionisation Working out the pH of a strong base Remember that: Since pH is a measure of hydrogen ion concentration how can a solution which contains hydroxide ions have a pH? To understand this you need to know about the ionic product for water Important: If you don't understand about the ionic product for water you must

11 12 2013To remove a hydrogen atom from water (which is a weak acid) you need a strong base Metals lower than calcium in the activity series are generally much too weak to remove protons from water even though they may still react with acids where the protons are not bound Not even magnesium reacts appreciably with cold water

Acids can also be either strong or weak Strong acids are highly corrosive and can cause burns Ex:Nitric Sulphuric Acid Weak acids are not so destructive Basic Substances Substances that contain a base are called basic substances Examples are Sodium Hydroxide Calcium Hydroxide Bases have many properties-They are bitter to taste Solutions of bases have a soapy touch They

Note that strong and weak means the amount the base will dissociate in water into component ions Calcium hydroxide: Ca(OH) 2 Calcium hydroxide is considered a strong to medium strength base It will completely dissociate in solutions of less than 0 01 M but weakens as concentration increases Calcium hydroxide is also known as calcium dihydroxide calcium hydrate hydralime hydrated

The chemical compounds that can convert strong acids or bases into weak ones They do so by removing or adding protons(H+) eg Carbonic acid- bicarbonate buffer system H+ + HCO3- - H2CO3 If there is an excess of H+ (acidic condition) HCO3- can function as a weak base and remove the excess H+ If there is a shortage of H+ (alkaline condition
