titration method to determine the percentage of calcium carbonate in toothpaste. Instead of using standard titration methods where an acid is titrated directly using a standard solution of a base‚ back titration is used because the sample to be analysed‚ CaCO3 does not dissolve in water. Hydrochloric acid and sodium hydroxide are the reagents used in this experiment. The precise measured amount of HCl is added to the weighted portion of toothpaste which is CaCO3. When the reaction between HCl and

percentage by mass of calcium carbonate‚CaCO3 in toothpaste using back titration technique. A known weight portion of toothpaste is obtained to react with known volume and concentration of standard acid solution. After completing the reaction‚ the resulting solution containing excess acid is back titrated with known volume and concentration of standard base solution. Determination of excess acid after reaction allow us to calculate the amount of acid react with CaCO3 in toothpaste sample. My result for

Limestone is a sedimentary rock composed of calcium carbonate (CaCO3). There are various types of limestone‚ as well as different methods for formation. When limestone is formed through precipitation of water‚ it is called chemical limestone. When limestone is formed from the shells or skeletons of dead marine organisms‚ it is called organic limestone. Limestone is soluble‚ so it is very common in Karst landscapes. Limestone has many uses‚ but it’s most common use is as a building material for architectural

of your house‚ draw chalk lines around your doorways and windowsills. Ants won’t cross a chalk line. Why? It’s not entirely clear‚ but some say the ants don’t like the particles sticking to their feet‚ while others say they’re averse to the calcium carbonate in the chalk. Whatever the reason‚ this nontoxic solution will keep ants outside where they belong. According to Leven Flickety(2006) There are two types of chalk paint: the first is paint made out of pieces of chalk‚ and the second is a type
