Do antacids have calcium hydroxide in them?
No, some have calcium carbonate or magnesium hydroxide, but not a strong base such as calcium hydroxide. However, medical doctors have prescribed calcium hydroxide as an antacid for severe acid reflux and severe heartburn. Interestingly, when a molecule of calcium hydroxide collides with a molecule of carbon dioxide at room temperature, it readily becomes calcium carbonate plus water: Ca(OH)2 + CO2 → CaCO3 + H2O However, when a solution of calcium hydroxide enters the human stomach, the primary chemical reaction is: Ca(OH)2 + 2HCl → CaCl2 + 2H2O [Calcium hydroxide reacts with hydrochloric acid at room temperature to become calcium chloride plus water]. Calcium hydroxide is water-soluble. Calcium carbonate is not neutral-pH-water-soluble at room temperature. However, calcium carbonate is acidic-water-soluble at room temperature. Because it is relatively harmless, calcium hydroxide is used as a preservative for glucomannan foods such as shirataki noodles and konnyaku cubes. Calcium chloride is also relatively harmless and is used as a preservative in many foods. Although not quite as delicious as real salt, calcium chloride gives foods a salty taste and greatly reduces or completely eliminates the need for sodium chloride in pickles. Calcium carbonate is the best-selling calcium supplement because it has a low price and also because it blocks about 65% to 70% of the absorption of heme iron, a cancer-causing and artery-clogging pro-oxidant. All other forms of calcium supplements can block only about 10% to 20% of the absorption of heme iron. People who swallow 300mg to 600mg of calcium daily as calcium carbonate are about 25% to 30% less likely to develop colorectal cancer than people who swallow other forms of calcium supplements or no calcium supplements at all. Caution: Do not swallow more than 600mg of calcium from calcium supplements daily. Numerous scientific studies now say that people who swallow more than 600mg of calcium from calcium supplements daily are almost twice as likely to die of cardiovascular problems compared to people who don't swallow any calcium supplements. Note: If you already suffer from calcified arteries, then eat a small amount (3oz is more than enough) of the Japanese fermented soybean food called, natto, every day. No other food and no prescription medicine can reverse arterial calcification. About half of all people with cardiovascular disease have calcified aortas when examined by chest X-ray.
What primary standard is used to titrate against potassium hydroxide?
The primary standard commonly used to titrate against potassium hydroxide is potassium hydrogen phthalate (KHP). It is a stable compound with a well-defined molar mass, making it suitable for accurately determining the concentration of a solution of potassium hydroxide.
What can do NaOH use as primary standard?
Sodium hydroxide easily absorb water and carbon dioxide.
Why sodium hydroxide is not a suitable regent to prepare a primary standard solution?
Sodium hydroxide is hygroscopic, meaning it easily absorbs moisture from the atmosphere, which can lead to inaccurate concentration measurements. It is also prone to reacting with carbon dioxide in the air, affecting its purity. Additionally, due to its strong caustic nature, it can be hazardous to handle during preparation of primary standard solutions.
How do you prepare one liter of a 1.25M ammonium hydroxide solution?
To prepare 1 liter of a 1.25M ammonium hydroxide solution, you would need to dissolve 42.14 g of ammonium hydroxide (NH4OH) in enough water to make a total volume of 1 liter. Measure out the correct mass of ammonium hydroxide, add it to a volumetric flask, and then add water while stirring until the final volume reaches 1 liter. Make sure to wear appropriate safety gear and handle ammonium hydroxide with caution due to its caustic properties.
WHAT IS THE ADA CODE FOR A pulpotomy?
The ADA code for a pulpotomy is D3220. This code is used to describe the procedure of removing the coronal portion of the pulp in a tooth, typically in primary teeth, to maintain the tooth's vitality and prolong its function.

What is the difference between a rct and a therapeutic pulpotomy?
Here are the key differences between a Root Canal Treatment (RCT) and a Therapeutic Pulpotomy, explained in 6 bullet points: Definition: RCT involves complete removal of the pulp (nerve tissue) from all canals of the tooth. Therapeutic Pulpotomy removes only the infected or inflamed pulp from the crown portion, leaving the healthy pulp in the roots intact. Purpose: RCT is done when the entire pulp (crown and root) is infected or dead. Pulpotomy is done to preserve vitality of the remaining healthy pulp, typically in early-stage infections or trauma cases. Procedure Complexity: RCT is more complex, involving cleaning, shaping, and filling all root canals. Pulpotomy is simpler and quicker, focused only on the pulp chamber. Tooth Vitality: After RCT, the tooth becomes non-vital (dead). After pulpotomy, the tooth remains vital (alive) if successful. Common in: RCT is common in permanent adult teeth. Pulpotomy is more commonly performed on primary (baby) teeth or young permanent teeth. Cost & Time: RCT is usually more expensive and requires multiple visits. Pulpotomy is less costly and often done in a single visit.
How much calcium does wheat bread have?

The primary function of the parathyroid glands is to regulate?
calcium

How soon can the failure of a liver transplantation be apparent?
Primary failure is apparent within one or two days.
Which other primary standard can be used to standardize sodium hydroxide other than KHP?
sodium hydroxide is a secondary standard because it absorb the moisture from the air and its concentration will change
State the name of chemical present in limestone?
The primary chemical present in limestone is calcium carbonate (CaCO3).
Why lime water turns turbid if expired in air is bubbled through it?
Lime water turns turbid when carbon dioxide (CO2) from the air is bubbled through it because the CO2 reacts with calcium hydroxide (the primary component of lime water) to form calcium carbonate (CaCO3). This calcium carbonate is insoluble in water and precipitates out, causing the solution to become cloudy or turbid. The reaction can be summarized as: Ca(OH)2 + CO2 → CaCO3 + H2O. Thus, the cloudiness is a result of the formation of solid calcium carbonate.
