hydrochloric acid
Since the word "acid" is used in the name, you can bet it is an acid, and not a base.
To determine the concentration of the acid (H2SO4) in a titration, you will need to know the volume of the acid used, the volume of the base added, and the molarity of the base. By using the balanced chemical equation of the reaction and the volume of the acid and base used, you can calculate the concentration of the acid.
MgOH2 is a base. It is also known as magnesium hydroxide and is commonly used as an antacid to neutralize stomach acid.
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
H3PO4 is an acid. It is known as phosphoric acid and is commonly used in beverages like cola to provide a tangy flavor.
an acid because it is an oxide not a hydroxide (that would be a base)
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.
Acid-base titration is used to determine the concentration of an acid or a base solution by neutralizing it with a solution of known concentration. It is commonly used in analytical chemistry to measure the amount of acid or base present in a sample. Titration is also utilized in industries such as pharmaceuticals, food and beverage, and environmental monitoring.
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
moles of acid = moles base = moles base/liter x liters of base used
