Why is sodium hydroxide used in titration?
Sodium hydroxide ionizes in water to form sodium ions and hydroxide ions; sulfuric acid ionizes to form hydrogen ions and sulfate ions. The reaction between hydroxide ions and hydrogen ions is rapid and complete; thus, the second requirement for an analytical titration is met.
What happens when sodium hydroxide reacts with hydrochloric acid?
Sodium hydroxide and hydrochloric acid react as shown in this equation. NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)
How do you find the concentration of HCl from titration with NaOH?
- Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3
- Amount of sodium hydroxide = 0
Which salt is formed by the reaction between hydrochloric acid and sodium hydroxide?
Sodium chloride
Examples: Sodium chloride and water are formed when hydrochloric acid reacts with sodium hydroxide (a strong base).How do you balance hydrochloric acid and sodium hydroxide?
Mass, we balance the equation HCl + NaOH = NaCl + H2O – chemical Balancer… 2 CO 3 + H 2 O 2 NaOH + HCl = H2O + NaCl limiting can!
Why does phenolphthalein turn pink in sodium hydroxide?
Ionization and the Phenolphthalein Indicator Ionized molecules attract other molecules with the opposite charge and repel those with the same charge. Adding hydroxide ions (OH-, as found in bases) will change the phenolphthalein into its ion and turn the solution pink.
What happens when HCl reacts with water?
When HCl is added to water, it donates an H+ ion to the water, leaving a Cl- ion in solution. This increases the H+ activity of the solution without increasing the concentration of OH- ions in the solution. Hence, the pH of water becomes more acidic; as you add an increasing amount of HCl, the pH gets lower.
What are the uses of HCl?
Oil production. HCL is used in the fracking process and in many gases and oil extraction processes to acidify a well to remove carbonate reservoirs, or limestones, from the rock or combined with other materials to dissolve quartz, sand and clay from rocks.
Is HCL an organic compound?
Answer: HCl ( Hydrochloric acid ) is an Inorganic compound. What is Organic compound and Inorganic compound ? Organic compound. An organic compound is virtually any chemical compound that contains carbon, although a consensus definition remains elusive and likely arbitrary.
What is the charge on hydrochloric acid?
HCl (hydrochloric acid) is a polar molecule because the chlorine is more electronegative than hydrogen due to which it attracts the bonded electron pair slightly nearer to it and gains a partial negative charge and hydrogen gains a partial positive charge. The dipole moment of HCl turns out to be 1.03 D.
