What example best describes a neutralization reaction?
When the same amount of acid is added to a certain amount of an equally strong base, then this is called neutralistion: every acidic H+ from the acid has reacted with every OH- (or basic anion) from this base.
What indicator would you use to determine the strength of a base?
Strong Acid - Strong Base titrationHCl(aq) + NaOH(aq) -----> NaCl(aq) + H2O(l) At equivalence the only species present will be NaCl(aq) & H2O(l)The solution of a salt of a strong acid and a strong base will have a pH=7NaCl(aq) will have a pH=7A suitable indicator would be bromothymol blue (pH range 6.2 - 7.6) or phenol red (pH range 6.8 - 8.4)Strong Acid - Weak Base titrationHCl(aq) + NH3(aq) -----> NH4Cl(aq) NH4Cl is the salt of a strong acid & a weak base, so a solution of NH4Cl will have a pH < 7 (NH4+ is a weak acid)A suitable indicator would be methyl orange (pH range 3.1 - 4.4) or methyl red (pH range 4.4 - 6.0)Weak Acid - Strong Base titrationCH3COOH(aq) + NaOH(aq) -----> CH3COONa(aq) + H2O(l) CH3COONa is the salt of a weak acid & a strong base, so a solution of CH3COONa will have a pH > 7 (CH3COO- is a weak base)A suitable indicator would be phenolphthalein (pH range 8.3 - 10.0) or thymol blue (pH 8.0 - 9.6)
What is HIO4 aq?
HIO4(aq) stands for periodic acid, which is a strong oxidizing agent commonly used in organic chemistry for oxidation reactions. It is a colorless, crystalline solid when in pure form and is soluble in water to form a clear solution.
7. Write chemical equations for the ion-forming reactions of the strong and weak bases in water. Identify the common ion that is produced in basic solutions.?
Strong bases, like sodium hydroxide (NaOH), completely dissociate in water to form hydroxide ions: [ \text{NaOH (s)} \rightarrow \text{Na}^+ (aq) + \text{OH}^- (aq). ] Weak bases, such as ammonia (NH₃), partially ionize in water: [ \text{NH}_3 (aq) + \text{H}_2\text{O} (l) \rightleftharpoons \text{NH}_4^+ (aq) + \text{OH}^- (aq). ] In both cases, the common ion produced in basic solutions is the hydroxide ion (OH⁻).
What is Ka for HCN(aq) H plus (aq) plus CN and ndash(aq)?
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.
Write the reaction when ammonium phosphate is put into water?
A strong electrolyte dissociates completely into ions in aqueous solution. When ammonium nitrite, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.NH4NO2(s) NH4+(aq) + NO2-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
What are the examples of strong alkalis?
Examples of strong alkalis include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These substances are highly reactive and can cause severe burns on skin and tissue.
____ HNO3 + ____ KOH → ?
HNO3(aq) + KOH(aq) --> KNO3(aq) + H2O(l) Because HNO3 is a strong acid, when it combines with a strong base it will react. When you deal with a problem like this the positive ions, H+ and K+ switch places.
What is the acid base reaction for HIaq and LiOHaq?
This reaction involves a strong acid (HI) and a strong base (LiOH). The hydroxide ion and the hydrogen ion will combine to form water. Therefore, the net ionic equation is simply H+(aq) +OH-(aq)----> H2O LiOH(aq) +HI(aq)----> LiI(aq) +H2O(l)
Write the reaction when lead cyanide is put into water?
A strong electrolyte dissociates completely into ions in aqueous solution. When lead cyanide, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.Pb(CN)2(s) Pb2+(aq) + 2CN-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
What is the reaction for HClaq and BaOHaq?
Since HCl is a strong acid and Ba(OH)2 is a strong base, the reaction that takes place is a simple neutralization reaction. The reaction is represented by the net ionic equation: H+(aq) + OH-(aq) ---> H2O This is the equation whenever any strong acid and strong base react.
What game is better aq or runescape?
I think its aq because there's a story and strong monsters. Plus, you can choose different classes to battle with. You get great armor, and lots more.
What is H2SO4(aq)?
Sulphuric Acid
What is the balanced equation of perchloric acid and sodium hydroxide?
Perchloric acid is a strong acid. Sodium hydroxide is a strong base. HClO4(aq) + NaOH(aq) ---> Na+(aq) + ClO4-(aq) + H2O(l) This is a balanced chmical reaction since the products and reacts have a 1:1 ratio.
What is KOH HNO3 balanced?
HNO3(aq) + KOH(aq) --> KNO3(aq) + H2O(l) Because HNO3 is a strong acid, when it combines with a strong base it will react. When you deal with a problem like this the positive ions, H+ and K+ switch places.
Write the reaction when barium bromide is put into water?
A strong electrolyte dissociates completely into ions in aqueous solution. When barium bromide, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.BaBr2(s) Ba2+(aq) + 2Br-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
Write the balanced NET IONIC equation for the reaction that occurs when perchloric acid and sodium hypochlorite are combined?
H3O+(aq) + ClO-(aq) HClO(aq) + H2O(l) Strong Acid + Weak Base 100% extent of reaction
