neutral
Basic. Na+ is the conjugate acid of a strong base, NaOH. The conjugate base of a strong acid is neutral. ClO- is the conjugate base of a weak acid, HClO, so it acts as a weak base in solution.
Calcium (Ca) is the element with a basic oxide of the type MO, which is calcium oxide (CaO). This compound, also known as quicklime, is commonly used to neutralize acidic soils by increasing the soil's pH level.
Personally, I use this method to determine if an ionic solid is acidic/basic/neutral. Let's take a look at the ions in this compound: Ca2+ and CO32- . Ca2+ is found in Ca(OH)2 , which is a very strong base. CO32- is found in H2CO3 , which is a weak acid. So, one ion comes from a strong base, while another comes from a weak acid. Overall, this compound must be basic. There are also other methods. You can add an acid to the solid. There is a reaction, so the solid must be basic. If you add a base, it doesn't react.
Basic stains are positively charged and bind to negatively charged components in cells, resulting in a darker coloration of the cells. Acidic stains, on the other hand, are negatively charged and bind to positively charged components in cells. The choice between basic and acidic stains depends on the type of tissue being studied and the specific cellular components that need to be visualized.
Perfectly pure water has a pH of 7, or "neutral". Water with dissolved minerals can be anywhere between about 6.5 and 8. In Citrus Heights, CA, where I live, our municipal water system provides water that's about 7.6, and this is the best tasting water I've ever had. FAR superior to bottled water or "spring" water.
Calcium chloride (CaCl₂) in aqueous solution is typically considered neutral. When dissolved in water, it dissociates into calcium ions (Ca²⁺) and chloride ions (Cl⁻), neither of which significantly affects the pH of the solution. Therefore, the resulting solution does not exhibit acidic or basic properties and remains close to neutral, usually around a pH of 7.
Calcium hydroxide, represented as Ca(OH)₂, is classified as a strongly alkaline compound when dissolved in water. It dissociates to release hydroxide ions (OH⁻), which increases the pH of the solution, making it basic. Therefore, a solution of Ca(OH)₂ is alkaline, not acidic or neutral.
Sodium bicarbonate, also known as baking soda, can be used to neutralize water if it is too acidic. Just a small amount of sodium bicarbonate can help raise the pH level of water to a more neutral range.
Calcium chloride (CaCl₂) is not a neutral compound; it is considered an ionic salt. When dissolved in water, it dissociates into calcium ions (Ca²⁺) and chloride ions (Cl⁻), which can affect the pH of the solution. Typically, calcium chloride solutions are slightly acidic due to the presence of the calcium ion, which can react with water to produce a small amount of hydrogen ions (H⁺). Thus, while it is not strongly acidic or basic, it is not classified as neutral.

Acidic Soil has a low pH . Remember the pH scale. 1 ( very acidic) ,, to 7 (neutral) ,, to 14 (very alkaline). Farmers often put lime on acidic soil in order to remove the acidity. As per the equation. 2H^+(aq) + Ca(OH)2(s) = Ca^(2+)(aq) + 2H2O(l) It should be noted that plants prefer acidic conditions, and other prefer more neutral/alkaline conditions.

Many oxides will react, especially in water, to form acids or bases. As a rule of thumb nonmetal oxides tend to be acidic while metal oxides tend to be basic or amphoteric. For example, carbon dioxide reacts with water to form carbonic acid so it is an acidic oxide. CO2 + H2O --> H2CO3 By contrast, calcium oxide reacts in water to form calcium hydroxide, so it is a basic oxide. CaO + H2O --> Ca(OH)2
