An acid is a solution that has an excess of hydrogen(H+) ions A base is a solution that has an excess of hydroxide(OH-) ions Another word for base is alkali The strength of an acid or base can be either strong or weak * An acid that has a very low pH (0-4) are known as Strong acids * A base that has a very high pH (10-14) are known as ### NaOH and HCl Titration Curves

NaOH is a strong alkali and HCl acid is a strong acid respectively To identify the equivalence point in the titration we use titration curves and indicators According to the concentration of acid and base solutions we have to choose correct curve and indicator ### Acid

HCl is the strong acid KOH is the strong base H 2 O is water KCl is a salt A weak acid and weak base generally result in a reversible reaction and the formation of a conjugate acid and a conjugate base as products The reaction between a weak acid and a weak base can be written as follows: Acid + Base Conjugate Base + Conjugate Acid ### WRITING TOTAL AND NET IONIC EQUATIONS

NH 3 (ammonia) is not a strong base It is considered a weak base because in solution it does not generate many hydroxide ions Although ammonia has no oxygen atoms in its molecule and therefore can't dissociate into hydroxide ions directly when dissolved in water the NH 3 molecule attracts a proton to form an ammonium ion NH 4 The proton is taken from the H 2 O water molecule leaving an ### What is the pH of a 0 050 M NaOH solution?

The pH is about 12 7 NaOH is a strong base meaning it will dissociate basically completely in solution to form Na^+ and OH^- ions in solution One mole of OH^- ions is created for every mole of NaOH that is dissolved If it's a 05 M solution of NaOH then it can also be interpreted to be a 05M solution of OH^- pOH (The pH scale for bases) can be found by taking the negative logarithm of ### lioh acid strong or weak base

Hydroxides of all alkali metals are strong base but LiOH is least basic because the dissociation of LiOH is minimum in water As LiOH is having maxmium covalent character because of Fajans' Rule LiOH is a weak base because it is more covalent due to small size DA: 47 PA: 13 MOZ Rank: 86 Is LiOH a strong or weak acid or base - Answers answers ### Acid

The pH is about 12 7 NaOH is a strong base meaning it will dissociate basically completely in solution to form Na^+ and OH^- ions in solution One mole of OH^- ions is created for every mole of NaOH that is dissolved If it's a 05 M solution of NaOH then it can also be interpreted to be a 05M solution of OH^- pOH (The pH scale for bases) can be found by taking the negative logarithm of ### Strong base LiOH with a weak acid HF LiOHaq HFaq The

LiOH(aq) + HF(aq) → LiF(aq) + H 2 O(l) (already balanced) Second separate the strong base (LiOH) into its constituent ions (since it will dissociate fully) LiF(aq) is a soluble salt based on rule 1 of our solubility rules (page 6 of Module 2 in the course notes) and it will dissociate fully ### List of the Strong Bases (Arrhenius Bases)

6/25/2019Strong bases are bases which completely dissociate in water into the cation and OH-(hydroxide ion) The hydroxides of the Group I (alkali metals) and Group II (alkaline earth) metals usually are considered to be strong bases These are classic Arrhenius bases Here is a list of the most common strong ### Strong and Weak Bases

We will use the following criteria to identify strong and weak bases Water-soluble ionic compounds that contain hydroxide ions are strong bases We will expect all other bases to be weak For example using these guidelines we would predict that sodium hydrogen carbonate NaHCO 3 is a weak base ### Heat of neutralisation of lioh and hcl at 25c is 34 868kj

When a strong acid and weak base is used it comes out to be somewhat lower than 57 1 KJ mol ⁻in this case it is 34 868 KJ mol ⁻ the reason for this lower energy is that some amount of energy is utilized in the complete ionization of weak base that is LiOH So the heat of ionization of LiOH=57 1-34 868
