Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong the chemical is‚ whether it is a stronger acid or a stronger base. pH is a measure of the concentration of protons (H+) in a solution. Danish Bio-chemist Soren Peter Lauritz Sørensen introduced his concept in 1909. The p stands for the German potenz‚ meaning power or concentration‚ and the H for the hydrogen ion (H+)

capable of removing grease or oil stains. It will be used for stains found in cloth. Sodium Bicarbonate is also used as a deodorant and can remove odours. It is also used as a replacement for softener when washing clothes with detergent. It is a weak base with a pH of 8.7. The main materials we will use for the experiment are: Sodium Bicarbonate (Baking Soda) Vinegar Water Oil Related Literature: Joy T. (n.d.).

Monica Mahmoudi 02072798 Bandaruk Mon-Wed 12:45 PH Balance in the Human Body As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids‚ to fruits‚ vegetables‚ seawater‚ beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2‚ obviously to digest food‚ wine is 3.5‚water is 7(neutral)‚ arterial

It approximates the base 10 logarithm of the level of calcite saturation. The Langeleir saturation examines the saturation concept using pH as the main determinant. The LSI obtained can be explained as the pH required to bring the water to equilibrium. Water that indicates

Research Question People may think of fruit as a sweet‚ healthy option for a snack. What those people do not know is that some of those fruits can be very damaging to their teeth and to their bodies. One reason for this is that a variety of commonly digested fruits are extremely acidic. This experiment will test the pH level of everyday fruits to see how acidic they actually are. When eaten‚ which fruit will have the lowest pH (be the most acidic)? Hypothesis A sign that a fruit is acidic is

Depending on the pH of the fruit or plant the pigment will give a different color. This pigment can be used to indicate pH. pH is the -log[H+]. Acids increase the concentration of hydrogen ions ([H+]) in a solution and therefore have a low pH. A base will increase the concentration of hydroxide ions ([OH-]) (decreasing the [H+]) in a solution and will have a high pH. Notes: *Another household item from which a pH indicator can be extracted is Ex-Lax. Phenolphthalein is a commonly used indicator

Conclusion “How can we test and treat the Acme wastewater?” We need to test the pH to see what the waters health is. We also need to see if there is any copper in the water‚ if there is‚ we need go go throught the procedure. If the water is turbid‚ we need to figure out a way to make it clear and clean. My hypothesis was partially correct and incorrect. It was correct because we did need to test the water to see if it was hazardous‚ and part of it did. We needed to fix that fast. It was partially

Procedure: The first part of this lab involved the standardization of the base NaOH with potassium hydrogen phthalate‚ or KHP. First‚ about 400 mL of NaOH (10 M) were poured into the 600-mL beaker. This was used to fill the burette. The 50-mL burette was rinsed through twice with 5 mL of NaOH. Then‚ the burette was mounted on the ring stand using a burette clamp and filled to 0 mL. Some of the NaOH was drained to fill the tip of the burette. The initial volume of NaOH‚ rounded to two decimal places
