Aqueous sodium carbonate titration with HCl solution. When HCl solution is added slowly to the Na 2 CO 3 solution, reaction happens in two stages. When dilute HCl is slowly added, first, sodium bicarbonate and sodium chloride are formed. Na 2 CO 3 + HCl → NaCl + NaHCO 3. Sodium bicarbonate is basic and can reacts with HCl furthermore.

Answer: NaHCO3+HCI->NaCI+H2O+CO2 CO2 gas can be checked by passing it through lime water.On passing lime water will be milky due to the formation of precipitate of calcium carbonate. Ca (OH)2+CO2->CaCO3+H2O Hope it helps. SEE ALL chevron right Advertisement Still have questions? Find more answers plus Ask your question New questions in Chemistry

(a) When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide and water are formed. Na 2CO 3(s)+2HCl(aq)→2NaCl(aq)+CO 2(g)+H 2O(l) (b) CO 2 gas is liberated during the reaction. When carbon dioxide gas formed in the form of brisk effervescence is passed through lime water, it turns the lime water milky.

A gas evolution reaction is a chemical process that produces a gas, such as oxygen or carbon dioxide. In the following examples, an acid reacts with a carbonate, producing salt, carbon dioxide, and water, respectively. For example, nitric acid reacts with sodium carbonate to form sodium nitrate, carbon dioxide, and water (Table \(\PageIndex{1}\)):

Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved.. 8,029 views Jun 23, 2020 Q.3 Metal compound A reacts with dilute hydrochloric acid to.

Write word equations and then balanced equations for the reactions taking place when (a) dilute sulphuric acid reacts with zinc granules. (b) dilute hydrochloric acid reacts with magnesium ribbon. (c) dilute sulphuric acid reacts with aluminium powder. (d) dilute hydrochloric acid reacts with iron filings.

An ore on treatment with dilute hydrochloric acid gives a smell like that of rotten eggs. What type of ore is this? How can it be concentrated?

When Zn is reacted with dilute sulphuric acid, zinc chloride is formed and hydrogen gas is liberated. This reaction is exothermic and hence heat is evolved in the reaction. Concept: Application of Activity Series in the Preparation of Hydrogen

Potassium, Sodium and Calcium will displace Hydrogen from acids (like H Cl). Silver, Copper, Gold , Platinum do not replace Hydrogen from dilute acids (like H Cl). This is so because of the reactivity of Hydrogen being more or less than those metals. Find Science textbook solutions? Science And Technology General Science SEE ALL Advertisement

Dilute samples to 100 µl; add 100 µl 10% trichloroacetic acid (TCA). Leave on ice for 20 min; centrifuge for 15 min in a microcentrifuge. Wash pellet with 100 µl of ice-cold ethanol, dry, and resuspend in 5x SDS-PAGE sample buffer (see table 5x SDS-PAGE sample buffer ).

As the gas formed is an effervescent carbon dioxide gas, it happens when Calcium Carbonate ( CaCO 3). reacts with hydrochloric acid (HCl). The carbon dioxide gas also acts as an extinguisher for fires. So, the burning candle is extinguished. The metal compound A, therefore, constitutes calcium carbonate. Thus metal compound A is CaCO3

Answer Acids and Bases React with Metals Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas.
