Is sodium hydroxide strong or weak acid?
Explanation: Strong bases are characterized by the fact that they dissociate completely in aqueous solution. In this case, sodium hydroxide, NaOH , is classified as a strong base because it dissociates completely in aqueous solution to form sodium cations, Na+ , and hydroxide anions, OH− .
How do you calculate the acidity of NaOH?
Thus, 0.00126 moles of NaOH (Step 2) would interact with 0.00063 moles of tartaric acid. Divide the number of moles of the acid (Step 4) by the aliquot volume and then multiply by 100 to calculate the acid amount in 100 ml of the solution. In our example, amount (C4H6O6)=0.00063 moles x 100 ml/15 ml=0.0042 moles.
What is the pH of 0.1 M sodium hydroxide?
13
Hence, the pH of 0.1 M NaOH is 13.
Is sodium hydroxide covalent or ionic?
Sodium hydroxide is a white solid. It melts at 318oC and boils at 1390 oC. It dissolves in water to produce a solution that conducts a current. In other words, NaOH is an ionic molecule.
How do you calculate acidity?
To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions).
How do you calculate pH from acidity?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
What is the pH of 1 molar sodium hydroxide solution?
The pH of 1M NaOH is 13.
Why sodium hydroxide is ionic?
Sodium hydroxide is represented by the chemical formula NaOH. It is an ionic compound because it is made of a metal ion, sodium (Na+) that is attracted to a nonmetal ion, hydroxide (OH-). When it is a solid, it is white and it has a high melting point of 604.4 degrees Fahrenheit.
