Hydroxide

c, phenolphthalein, methyl orange, deionized water and the following chemicals: sodium hydroxide, potassium hydrogen phthalate, hydrochloric acid and sodium bicarbonate. When it comes to these chemicals, make sure to wear the general protective personal equipment and handle with caution because these chemicals can burn. (MSDS Solution Center) For week one, the students first had to prepare the sodium hydroxide and the hydrochloric acid. Both of these were done by taking a graduated cylinder and…

sodium hydroxide solution in part one of the experiment. It was known that the potassium hydrogen phthalate and sodium hydroxide should have had a 1:1 stoichiometric molar ratio. Potassium hydrogen phthalate was used as the primary standard because it is a very pure concentrated substance that can be predicted. However, the sodium hydroxide is too difficult to be measured because of its tendency to absorb water vapor. This is one area where error can be noted; at times the sodium hydroxide was…

the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to measure the amount of pure water we decide that we need. A weight boat to be able to measure the sodium hydroxide(NaOH) on the triple beam balance. We also used a beaker to put our amount of pure…

differentiate acids and bases? How do we know if a substance is an acid or a base? There are different methods to discover whether a substance is an acid or a base. One of the methods is by using an acid-base indicator or by identifying hydrogen or hydroxide ions in a substance’s chemical formula. Certain materials such as a plastic template, red litmus paper, blue litmus paper, phenolphthalein, universal indicator, and a pH chart can be used to help us distinguish acids and bases. Before…

has more hydrogen ions, it is an acidic solution, and if the solution has more hydroxide ions, it is a base (636). Acids and bases can be strong or weak. Strong acids are able to conduct electricity, and all the HCl molecules in the solution can be ionized completely (644). Weak acids produce fewer ions, and therefore do not conduct electricity well (645). Strong bases can dissociate completely into metal ions and hydroxide ions, while weak bases can only ionize partially (648). This means…

a titration was carried out using a standard solution of hydrochloric acid to establish the molarity of a solution of sodium hydroxide. The concentration of acid in the gastric juice sample was determined using that solution of sodium hydroxide. The pH of gastric juice was then calculated and compared with the value determined by…

with different volumes of sodium hydroxide. Introduction When looking at the coefficient of balanced equations, stoichiometry is seen. Coefficients represent the number of moles, equivalent to the mass of an atom, of the products and reactants. Stoichiometry was demonstrated in this experiment to determine the relationship between the testing agents. A polyprotic acid or base is used because it is able to react with varying molar equivalents of sodium hydroxide. In…

Alcalak, and Medi-first were indirectly titrated with sodium hydroxide (NaOH), which is a strong base. By using the back titration technique, the amount…

a Weak Acid Solution • Obtain an unknown acid solution (90 mL) and three 250 mL beakers. Make sure the beakers are clean. • Acquire 0.1 M of NaOH solution for this experiment and make sure to determine the specific molar concentration of sodium hydroxide utilized. • Obtain a buret and make sure to rinse it with tap water, deionized…
