In she the ph of the acid solution should be

A comic book villain is holding you at gun point and is making you drink a sample of acid. You can add as much of the strong base to the strong acid as you want, and you must then drink the solution.

The pH scale is logarithmic and inversely indicates the activity of hydrogen ions in the solution. The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. The pH of aqueous solutions can be measured with a glass electrode and a pH meter or a color-changing indicator. Measurements of pH are important in chemistry , agronomy , medicine, water treatment, and many other applications. The concept was later revised in to the modern pH to accommodate definitions and measurements in terms of electrochemical cells. The letter p could stand for the French puissance, German Potenz, or Danish potens , all meaning "power", or it could mean "potential".

A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing. They are added to various solutions to determine the pH values of those solutions. A pH of 7 indicates a neutral solution like water. A pH less than 7 indicates an acidic solution and a pH greater than 7 indicates a basic solution. Recall that pH indicators are not only natural dyes but also weak acids. The dissociation of the weak acid indicator causes the solution to change color. It is important here to note that the equation expressed in figure 4 is in equilibrium, meaning Le Chatelier's principle applies to it. For example, common indicators such as phenolphthalein, methyl red, and bromothymol blue are used to indicate pH ranges of about 8 to 10, 4. On these ranges, phenolphthalein goes from colorless to pink, methyl red goes from red to yellow, and bromothymol blue goes from yellow to blue. For universal indicators, however, the pH range is much broader and the number of color changes is much greater. See figures 1 and 2 in the introduction for visual representations. Usually, universal pH indicators are in the paper strip form. Additionally, pH indicators can be found in nature, so therefore their presence in plants and flowers can indicate the pH of the soil from which they grow. Nature contains several natural pH indicators as well: for example, some flower petals especially Roses and Hydrangeas , certain fruits cherries, strawberries and leaves can change color if the pH of the soil changes.

The unified absolute pH scale is based on the absolute chemical potential of the proton, as defined by the Lewis acid—base theory.

Given the pH values for the four solutions, she can easily determine the solution that should be identified as a base by looking for the highest pH value. In this case, solution D has a pH of 9, which is the highest among the four solutions.

Strong acids and bases are compounds that are almost completely dissociated in water, which simplifies the calculation. Q: Which of the following solutions is a buffer? A standard hydrogen electrode SHE is an electrode used as a reference in electrochemical measurements.

A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing. They are added to various solutions to determine the pH values of those solutions.

Retrieved 13 March Every amino acid has a carboxyl group and an amino group, and each group can exist in an acidic form or a basic form depending on the pH of the solution in which the amino acid is dissolved. Much more complicated expressions are required if activities are to be used. One advertisement says that the medicine provides relief for acid indigestion and sour stomach. Pour about 15 mL of this dilute universal indicator solution into a clean cup for each student group. You make a 0. Chapter 1 : Matter—Solids, Liquids, and Gases 1.
