    Salt Water Lab

    • 2 Pages

    The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh

    Let’s Make Salt Purpose: Could NaCl be made using NaHCO3‚ hydrochloric acid‚ and a boiling chip? Hypothesis: If I combined NaHCO3‚ hydrochloric acid‚ and a boiling chip I think it will form NaCl because when you balance the equation it makes a new chemical reaction. Materials needed: test tube cleaner‚ test tube‚ test tube tongs‚ hot plate‚ a scale‚ graduated cylinder‚ water‚ goggles‚ fire retardant glove‚ beaker‚ test tube holder‚ a scoopula‚ hydrochloric acid‚ sodium bicarbonate‚ soap‚ pipette

    In this Laboratory experiment‚ my lab partner Alexander and I were able to understand thoroughly the physical and chemical properties of salt (NaCl) and sand (SiO2). Followed by the right procedure we were able to design and test out the components of both NaCl and SiO2 in order to separate the unknown mixture that we were able to find out about. We were also given the task to provide the percent composition of the mixtures. Therefore‚ the separation of components among this experiment allowed us

    Aim: The aim of this experiment was to develop a technique to separate a mixture of sandsaltiron filings‚ kerosene and water. Hypothesis: It was hypothesized that the heterogeneous mixture of saltsand kerosene‚ iron fillings and water will be effectively separated. It is also predicted that there will be a decrease in each of the substances as a results of sources of error.

    Aim: To Find and test the Iron content in different food sources INTRODUCTION: A Redox titration was used in order to perform this experiment. Reduction/oxidation (redox) process occurs when electrons are transferred from a donor species (the reducing agent) to another acceptor species (the oxidizing agent). It happens between an analyte and a titrant. A redox titration is done just as a normal titration is done‚ however instead of titrating an acid against a base‚ an oxidizing agent is titrated

    Potentiometric Titrations Accuracy The accuracy of a potentiometric analysis is limited by the measurement error for the cell’s potential. Several factors contribute to this measurement error‚ including the contribution to the potential from interfering ions‚ the finite current drawn through the cell while measuring the potential‚ differences in the analyte’s activity coefficient in the sample and standard solutions‚ and liquid junction potentials. Errors in accuracy due to interfering ions

    Hydrated Salt Lab Report

    • 368 Words
    • 2 Pages

    In this lab‚ we used Bunsen burners to heat up a hydrated salt in order to determine the percentage of water inside of this hydrated salt. We heated up the salt in order to boil off the water‚ which allowed us to find the weight of the CuSO4 by itself. By comparing this final weight with the original weight and subtracting the difference‚ we were able to compile data about how much the weight of the hydrated salt decreased as the water gradually boiled away. In doing so‚ we were able to find the

    In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

    The litmus paper and the pH probe determined the salt solutions’ pH levels. When the blue litmus paper was dipped into ammonium chloride‚ the paper was changed to red whereas the red litmus paper stayed the same indicating that the solution was acidic. PH levels shown through pH probe also ranged between 5.5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the
